In ∆ABC , if AB = AC and ∠B=80° then ∠C is equal to
a) 20° b) 40° c) 60°
Answer:
Here,
given, angle B = 80 degree
in ABC triangle, AB = AC
that means angle B = angle C
so angle C must be 80 degree
Step-by-step explanation:
I guess, the options are wrong
or,
may the question asked for angle angle A
which will be = 180- (80+80) = 180 - 160 = 20 degree (option a)

Let's use the furthest left point on the triangle to figure out the translation.
Blue triangle = (-5,1)
Black triangle = (-3,-1)
To get from -5 to -3 we moved the triangle 2 units to the right, which means that we added 2.
To get from 1 to -1, we moved the triangle 2 units down, which means we subtracted 2.
Rule: {2, -2}
Hope this helps!

Answer:
70°
Step-by-step explanation:
An euclidean triangle (a triangle on a straight plane) has sum of three angles equal to 180°.
When we talk about a triangle, we usually talk about an euclidean one.
There are also a non-euclidean triangles which are a triangle on circular plane which has sum of angles above 180° and one that is a hyperbolic triangle version which has sum below 180°.
Back to the question, since we know that the triangle is an euclidean one and thus has the sum equal 180°.
x+20+40+2x-30 = 180
Combine like terms:
3x+30=180
Subtract both sides:
3x+30-30=180-30
3x=150
Divide both sides by 3.
3x/3 = 150/3
x = 50
Since we want to find angle B which has measure of 2x-30, substitute x = 50 in 2x-30.
2(50)-30 = 100-30 = 70
Therefore angle B is 70°
The x-intercepts and vertex of the quadratic relation y = –(x + 3)(x + 5) are:
a) x-intercepts are 3 and 5; vertex is (4, 0)
b) x-intercepts are –3 and –5; vertex is (–4, 9)
c) x-intercepts are 3 and 5; vertex is (4, –63)
d) x-intercepts are –3 and –5; vertex is (–4, 1)
Answer:
d) x-intercepts are –3 and –5; vertex is (–4, 1)
Step-by-step explanation:
parabola are the vertex findings -4
we find these using formula m +n / 2
m+ n = -3 -5 / 2 = -4
m+n / 2 = -8/2 = -4
xv = -4
plug in -4 to find yv
(x+5)
(-4 + 5)
yv = 1
solve the simultaneous equation
3x + y = 8
x - 3y = 11
Answer:
x = 7 / 2, y = - 5 / 2
Step-by-step explanation:
3x + y = 8 ------> equation 1
3 ( 3x + y = 8 )
9x + 3y = 24 ------> equation 2
x - 3y = 11 ------> equation 3
Add equations 2 & 3,
9x + 3y = 24
x - 3y = 11
_________
10x + 0 = 35
10x = 35
x = 35 / 10
x = 3.5
Substitute x = 3.5 in equation 1,
3x + y = 8
3 ( 3.5 ) + y = 8
10.5 + y = 8
y = 8 - 10.5
y = - 2.5
x = 3.5
= 35 / 10
x = 7 / 2
y = - 2.5
= - 25 / 10
y = - 5 / 2

Answer:
Step-by-step explanation:
a^2 + b^2 = c^2
3.2^2 + b^2 = 18.9^2
10.24 + b^2 = 357.21 Subtract 10.24 from both sides
b^2 = 357.21 - 10.24
b^2 = 346.97
sqrt(b^2) = sqrt(346.97)
b = 18.62
Perimeter = 2*a + 2*b
Perimeter = 2*3.2 + 2*18.62
Perimeter = 6.4 + 37.25
Perimeter = 43.65

What type of special angle pair is represented
A) corresponding
B) consecutive interior
C) alternate exterior
D) alternate interior
Answer:B cointerior
Step-by-step explanation: if you look the angle make a C or backward C pattern and are both on the inside of parallel lines. the are supplementary which means they will add to 180. there is also Z and F patterns that create equal angles

A regular octagon is shown below. Suppose that the octagon is rotated clockwise about its center so that the vertex at Y is moved to 7. How many degrees
does the octagon rotate?
Answer:
I believe it says the vertex at Y is moved to T:
the angle of each side changes by 360 / 8 = 45 at each vertex
If 3 vertices separate Y and T the the total rotation would be
3 * 45 = 135 deg
The octagon rotated 135 degree.
What is an Octagon?An octagon is a polygon with eight sides.
The total angle at the center is 360 degree and for a regular octagon, the angle made by each side is equal to 360/8 = 45 degree.
The octagon STUVWXYZ is rotated clockwise such that, the vertex Y moves to T.
Movement of Y to T is moving 3 steps clockwise
= 45* 3
= 135 degree

is y=x2-1 a linear function
Answer:
No, it is a quadratic function
Step-by-step explanation:
If you mean y=x²-1, then it is a quadratic, since we have x to the 2nd power.
If we had an equation in the form of y=mx+b, where m is the slope and b is the y intercept, it is linear.
An example of a linear function would be, y=6x-5

The students were helping decorate a bulletin board for the missionary conference. Christi use 5/16 of a roll of blue paper and sandy used 1/8 of the roll. How much more paper did Christi use than sandy?
Answer:
Christi used 3/16 more of the roll than Sandy did.
Step-by-step explanation:
First, you'll need to make the denominators the same. I htink it's called GCF or Greatest common factor.
16:16,32...
8:8,16...
That was quick, anyways now perform these equations:
1/8=8 x 2 = 16, 1 x 2 = 2
1/8 is now 2/16. Now you can easily compare the equations.
Since 5/16 already has 16 as it's denominator you make no changes to it.
5/16 - 2/16 = 3/16
now you can simplify your answer: 3/16 = 3/16 it's already at it's simplest form.
Your answer would be 3/16.
