Answer:

42+x=90

Step-by-step explanation:

Complementary angles are when their measures add up to 90°

Therefore, if angle a is 42° you would find angle b by subtracting 42° from 90° which is shown in equation number three.

What is the measure of angle TRV?<br><br> 20°<br> 50°<br> 60°<br> 130°

srv is a straight line so angleSRV=180
TRV and SRT make up SRV so TRV + SRT = SRV.
(x-10) + (2x+10) = 180.
the 10s cancel each other out so 3x = 180
so x=60 bc 180/3=60. sub 60 for x in TRV and u get 130. sub 60 for x in SRT and you get 50, which, with 130 makes 180, so the answer is correct!
