M∠GHI=6x° and m∠LMN=9x°. If ∠GHI and ∠LMN are supplementary, what is the measure of each angle?

72° and 108°

Step-by-step explanation:

We know that GHI + LMN = 180°. We can rewrite it as:

6x + 9x = 180°

15x = 180°

x = 12

Now we can find GHI = 6x = 72° and LMN = 9x = 108°

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.
