<PRE><B>Question 270368</B>
I need to show the work and answer the problem But im a little stuck on nhow to do it. 
angles A and B are complementary. Find m angle A and m angle B 
1. measure of angle a = 3/4x - 13
measure of angle b = 3x -17 

Since angles a and b are complementary a = 90 - b. So we have:

1.) 90 - b = 3/4x - 13
2.) b = 3x - 17

Substitute 3x - 17 for b from 2.) in 1.) giving:

90 - (3x - 17) = 3/4x - 13

Now you can solve for x then calculate a and b.

The second question is similar except the angles are supplementary so
a = 180 - b.  </PRE>
