Find the missing side of each triangle. Round your answers to the nearest tenth if necessary. (Please Show your work)
Answers
Answer:
11.2 mi
Step-by-step explanation:
1. We can use the Pythagorean Theorem (a^2 + b^2 = c^2) to find the missing leg, b, of the triangle.
[tex]9^2 + b^2 = 14.4^2[/tex]2. (Solving)
Step 1: Simplify both sides of the equation.
[tex](9*9)+b^2 = 14.4 * 14.14[/tex] [tex]81 + b^2 = 207.36[/tex] [tex]b^2 + 81 = 207.36[/tex]Step 2: Subtract 81 from both sides.
[tex]b^2 + 81 - 81 = 207.36-81[/tex] [tex]b^2 = 126.36[/tex]Step 3: Take the square root of both sides and round to the nearest tenth.
[tex]\sqrt{b^2} = \sqrt{126.36}[/tex] [tex]b = \sqrt{126.36}[/tex] b ≈ 11.2Therefore, x = 11.2 mi.

Answers
Answer:
x=25
Step-by-step explanation:
they are supplementary and adjacent, thus you do 4x-3+3x+8=180, simplify and get 7x+5=180, subtract 5 from 180 which is 175, then ending up with 7x=175 and 175/7 is 25.

Find the equation of the quadratic function given the vertex and a point on the parabola.
v= (3,0), p=(1,4)
Answers
Answer:
y = x² - 6x + 9
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Here (h, k ) = (3, 0 ) , then
y = a(x - 3)² + 0
To find a substitute (1, 4) into the equation
4 = a(1 - 3)² = a(- 2)² = 4a ( divide both sides by 4 )
1 = a
y = (x - 3)² = x² - 6x + 9

Answer:
63
Step-by-step explanation:
A median bisects the side that it is drawn to, so
DM = ME4x - 10 = 3x + 5x - 10 = 5x = 15So, FN = 4(15) + 3 = 63.
Once again, since a median bisects the side it is drawn to, NE = 63.

let the interior angles of the given triangle be angle a b c respectively.
116+a=180 (Sum of angles on a straight line.)
a=180-116
a=64
.......
112+b=180(Sum of angles on a straight line.)
Sum of angles on a straight line.)b=180-112
b=68
....
angle a +b+c=180 (Sum of angles of a triangle)
64+68+c=180
c=180-132
c=48
.,....
angle c +X =180(Sum of angles on a straight line.)
48+X=180
X=132
Therefore the value of X is 132.
2.
solution,
Let the remaining interior angle of the given triangle be y.
Then,
y+108=180(Sum of angles on a straight line.)
y=72
Again,
2x+X+y=180(Sum of angles of a triangle)
3x+72=180
3x=108
X=108÷3
X=36
Therefore the value of X is 36.
3.
solution,
let the remaining interior angle of the given polygon be a and b .
Then,
100+b=180(Sum of angles on a straight line.)
b=80
......
Again,
a+b+110+90=360(Sum of interior angle of the polygon)
a+80+200=360
a+280=360
a=80
.....
a+X=180(Sum of angles on a straight line.)
80+X=180
X=100
Therefore the value of X is 100.
4.
solution,
The given triangle is an isosceles triangle.So their base angles are equal .
43+43+X=180(Sum of angles of a triangle)
X=180-86
X=94
Therefore the value of X is 94.
5.
solution,
Opposite angles of a parallelogram is equal
So ,
X=125
Therefore the value of X is 125.
6.
solution,
Let the remaining interior angle of the triangle be a .
Then,
a+117=180 (Sum of angles on a straight line.)
a=63
Now,
a+X+83=180(Sum of angles of a triangle)
63+83+X=180
146+X=180
X=34
Therefore ,the value of X is 34.

2/5 or .4 as a decimal
Step-by-step explanation:
we can't do anything in the Parentheses so we distribute the -2.5 giving us the equation
-10x+10=6
we subtract both sides by 10
so now our equation is
-10x=-4
we divide both sides by -10
this leaves us with -4/-10 which is simplified to 2/5 or .4 as a decimal

Isosceles Right Triangle Reflection to prove ASA Congruence
1. Answer the following questions:
A. What line of reflection did you choose for your transformation?
- I used the y-axis as my line of reflection.
B. How are you sure that each point was reflected across this line?
- I am sure because the sides are all opposite, but the numbers stayed the same.
C. What reflection rule did you apply to your triangle?
- (x, y) ➟ (-x, y)
2. What other properties exist in your triangle? Discuss at least two theorems you learned about in this module that apply to your triangle. Make sure to show evidence by discussing your triangle's measurements.
- I learned that if two sides of my triangle are congruent then the angles opposite of them are congruent as well. The third angle is 90 degrees.
3. Did your triangle undergo rigid motion? Explain why.
- Yes, it did. It did because the distance and position stayed the same while the points and the plane moved.

A. We have chosen x-axis as a line of refection.Reflection along x-axis idicates rotation of 180° along x axis.
B. We are sure that each point is reflected accross this line because base has same magnitude but the signs have changed and rotation along x-axis doesn't change the value of y co-ordinate.
C. Rotaion along X-axis by 180°.
