Question

What would be the measure of angle A?

A. 70 degrees
B. 79 degrees
C. 55 degrees
D. 44 degrees

Answer 1

D

Explanation:

The sum of the 3 angles in a triangle = 180°

Sum the 3 angles and equate to 180

4x + 8x - 9 + 57 = 180, that is

12x + 48 = 180 ( subtract 48 from both sides )

12x = 132 ( divide both sides by 12 )

x = 11

Thus

∠ A = 4x = 4 × 11 = 44° → D
