Find an angle measure of angle A and B <br> A (5y-3) <br> C (3y+27)
Mashcka [7]

The measure of angle A and C will be 94.5° and 85.5°.

<h3>How to calculate the angle?</h3>

(5y - 3) + (3y + 27) = 180

Collect like terms

5y + 3y - 3 + 27 = 180

8y = 180 - 27 + 3

8y = 156

y = 156/8 = 19.5

(5y - 3) = (5 × 19.5) - 3 = 94.5

(3y + 27) = (3 × 19.5) + 27 = 85.5

Therefore, the measure of angle A and C will be 94.5° and 85.5°.
