Can someone help me please ?!?

Answers:

Explanation:

The smaller angles QRT and TRS combine to the angle QRS which is 90 degrees.

(angle QRT) + (angle TRS) = angle QRS

(2x) + (8x) = 90

10x = 90

x = 90/10

x = 9

We'll then use this x value to find each angle

As a way to check the answer,

angle QRT + angle TRS = 18+72 = 90

so the answer is confirmed.

i think is g(1)=-1.

hope that i can
