Answer:
This question is maybe r2+ =>()0?
Step-by-step explanation:
Answer:
The solution is 
Step-by-step explanation:
We have the following equation:

Elevating both sides to 2, we can isolate x




Checking

Y = 1st angle
X = 2nd angle
Y = 3X - 16
90 = X + Y
90 = X + (3X -16)
Do some algebra and X=26.5
So substitute x back in to find y, and Y=63.5
