32) First note that (8x + 26) and 3x are supplementary angles (add to 180°) and solve for x.
8x + 26 + 3x = 180
11x + 26 = 180
11x = 154
x = 14
Then note that (5y + 38) and 3x are also supplementary angles and substitute x = 14 and solve for y.
5y + 38 + 3x = 180
5y + 38 + 42 = 180
5y + 80 = 180
5y = 100
y = 20
You can verify these answers by substituting them back into the original expressions. We get:
8x + 26 = 138
3x = 42
5y + 38 = 138
33) This is similar to 32). Here, we get:
2y + (3y + 30) = 180
5y = 150
y = 30
(4x - 100) + (x + 5) = 180
5x - 95 = 180
5x = 275
x = 55
Once again, you can verify these answers by substituting them back into the original expressions.
