What is the answer?

hammer [34]

Answer:

$x = 27$

Step-by-step explanation:

Angle A and angle E are the same value, therefore you could replace angle E with angle A. So that would make a triangle with angle C, angle D, and angle A. Knowing the sum of all angles in a triangle is 180, we can make an equation representing this.

$3x - 10 + 2x + 10 + 45 = 180$

Now simply silve the equation to find x.

$5x + 45 = 180 \\ 5x = 135 \\ x = 27$

There is your answer.

NEED ANSWER RIGHT NOW!!!

Answer:

$\displaystyle [-1, 2], [1, 3], [1, 1], [0, 0]$

Step-by-step explanation:

All you have to do is divide each group of coordinates by 4:

$\displaystyle [4, 8], [12, 12], [12, 4], [8, 0] → [1, 2], [3, 3], [3, 1], [2, 0]$

However though, the centre of dilation is at the origin $\displaystyle [0, 0],$ so deduct all x-coordinates by 2 to get these ordered pairs:

$\displaystyle [-1, 2], [1, 3], [1, 1], [0, 0]$

I am joyous to assist you anytime.
