Finding Angle Measures When Parallel Lines Are Cut By a Transversal
Answer and Explanation:
m∠1 = 43° because opposite angles are congruent
m∠2 = 137° because ∠2 and 43° are supplementary, so m∠2 + 43° = 180°
m∠3 = 137° because opposite angles are congruent, so m∠3 = m∠2
m∠5 = 43° because alternate angles are congruent
m∠6 = 137° because ∠5 and ∠6 are supplementary, so 43° + m∠6 = 180°
m∠7 = 137° because alternate exterior angles are congruent, so m∠7 = m∠2
m∠8 = 43° because alternate exterior angles are congruent, so m∠8 = m∠1
Answer:
angle 1: 43
angle 2: 137
Step-by-step explanation:
Lets find angle 1 first :)
Since oposite diagonal angles are the same, this will make angle 1 43 degrees :)
Now lets find angle 2!
Since 1 was 43 degrees, and a flat line is 180 degrees we must subtract!
Lets do that now!
180 - 43 = 137
Angle 2 will be 137 degrees!

A train passes through a 360 m long tunnel completely in 24 seconds. It passes through another tunnel 216 m long completely in 16 seconds at the same average speed. Find the length of the train.
The average speed of the train is 18m/sec and the length of the train is 72 m.
let x represent the length of the train.
and 'S' be the speed of the train.
Given, that the train passes through 360 m long tunnel completely in 24 sec.
⇒ 360+x/24 = s
⇒ 24s = 360+x ...eq(1)
And also given that it passes through another tunnel 216 m long completely in 16 sec.
⇒ 216+x/24 = s
⇒ 16s = 216 + x .... eq(2)
⇒ subtract eq(1) from eq(2)
⇒ 24s = 360 + x
16s = 216 + x
8s = 144
s = 18 m/sec
length of the train: 24s = 360+x
24(18) = 360+x
432 = 360+x
x = 432-360
x = 72m
Hence the length of the train is 72 m.

A polygon has 7 sides. The interior angle measures are 130°, 118°, 135°, 128°, 126°, 134°, and x°. Find the value of x.
Answer:
129 degrees.
Step-by-step explanation:
The Sum of all the interior angles of an a-sided polygon is always (n−2) × 180 degrees.
As this is a seven-sided polygon, the sum of its interior angles is (7−2) × 180 degrees = 5 × 180 degrees = 900 degrees.
Step 1: Find the sum of six of the angles is 130 degrees, 118 degrees, 135 degrees, 128 degrees, 126 degrees, and 134 = 771 degrees
Hence the seventh angle is x = 900 degrees − 771 degrees= 129 degrees.

To write the given equation in slope-intercept form, rearrange the equation to isolate y.
Add 3x to both sides of the equation:

Divide both sides of the equation by 4:
[tex]\implies \dfrac{4y}{4}=\dfrac{3x-3}{4}[/tex]

an airplane is travelling down a runway at a speed of 66 feet per second, when it begins to slow down. the airplane decelerates at a constant rate of 6 feet per square second. how many feet does the airplane travel before it stops? (do not include units in your answer.
With deceleration of 6 ft/s² and initial speed of 66 ft/s, the airplane will stop after travelling 363 ft.
Use the equation of motion:
v² = u² + 2 · a · s
Where:
v = final velocity
a = acceleration
u = initial velocity
s = distance
Deceleration is a negative acceleration.
Parameters given from the problem:
u = 66 ft/s
a = - 6 ft/s²
v = 0 since the airplane stops.
Plug these parameters into the formula:
v² = u² + 2 · a · s
0 = 66² + 2 · (-6)· s
s = 66² / 12
s = 363 ft.

The equation of the required perpendicular line is y = (-5/4)x - 30.
We are given an equation. The equation is linear in nature. The equation represents a straight line. The equation of the given straight line is y = (4/5)x + 23. We need to find the equation of the straight line that is perpendicular to the given line and passes through the point that has coordinates (-40, 20).
The slope of the given line is 45. Let the slope of the required perpendicular line be represented by the variable "m". The slope of the perpendicular line must be the negative reciprocal of the slope of the given line.
m = -1/(4/5)
m = -5/4
The equation of the required line is of the form y = mx + c.
y = (-5/4)x + c
We know that this line passes the point (-40, 20).
20 = (-5/4)(-40) + c
20 = 50 + c
c = -30
Hence, the equation of the required line is y = (-5/4)x - 30.

Answer:
No real zeros.

The equation of line passing through the point (-3, -1) and is perpendicular to the line y = -x/2 - 5 is y = 2x + 5
What are perpendicular lines?perpendicular lines are defined as two lines that meet or intersect each other at right angles (90°).
In such lines the product of their gradients is -1.
if y = -x/2 - 5
then comparing the equation with y = mx + c
it means slope(m) = -1/2
so the slope(p) of the second line perpendicular to the above line will be
p x m = -1
p = -1/m
p = -1 ÷ -1/2
p = 2
so if x = -3, y = -1 and substituting these values into the equation of line , y = mx + c becomes
-1 = 2 x (-3) + c
-1 = -6 + c
collect like terms
c= 6 - 1
c = 5
Equation of the second line becomes,

The equation of the parabola, in vertex form, that represents the ball's distance, y, from the hole, x seconds after the ball is hit is
y = (-2m/s^2)t^2 + (-2m/s)t + 6m
Define quadratic equation.ax² + bx + c = 0 is a quadratic equation, which is a second-order polynomial equation in a single variable. a 0. It has at least one solution because it is a second-order polynomial equation, which is guaranteed by the algebraic fundamental theorem. The answer could be simple or complicated.
Given,
Assume for the moment that the hole is located at y = 0m, where x represents the time variable.
We are aware of:
The vertices are (-1s, 8m).
x in seconds and y in meters, I presume
The ball enters the hole at time x = 1s, hence we also have the following point:
(1s, 0m).
The vertex of the quadratic equation y = ax2 + bx + c is located at:
x = -b/2a,
Next, we have:
-1 = -b/2a.
Next, we have equations for trees:
8m = a(-1s)2, b(-1s), and c
0m = (a(1s)2) + (b(1s)2) + (c)
-1s = -b/2a.
The third equation should have one variable isolated first, and then it should be substituted in one of the other two:
1s2a = b.
Therefore, we can change b to bi 1s2a in the first two equations.
8m = 1s×2a×1s - a×1s2a1s + c
0m = 1s×2a×1s + a×1s×2a + c
We can combine the two equations to get:
8m is equal to a(1s2 - 2s2) + c, or a×1s2 - c.
0m is equal to a(1s2 + 2s2) + c, or a×3s2 + c.
We may quickly remove c from the second equation and then substitute it in the first equation:
c = -a3s^2
The initial equation is now:
8m is equal to -a×1s2 - a×3s2 - a×4s2.
a = 8m/-4s^2 = -2m/s^2.
We can now determine the values of c and b using a.
c = -(-(-2m/s2)*3s2)*3s2 = 6m.
B is equal to 1s*2a = 1s*(-2m/s2) = -2m/s.
The equation is then:
y = (-2m/s^2)t^2 + (-2m/s)t + 6m
