Question

∠1 and ∠2 are complementary. If m∠1 = (x + 3)° and m∠2 = (4x - 8)°. Find the value of x

Answer 1

I hope this helps you



complementary angles sum is 90 degree



x+3+4x-8=90


5x=95


X=19

Answer 2

complementary = angles add up to 90.

two angles are (x+3) and (4x-8)

Therefore:

90 = (x+3) + (4x-8)

Solve for x.

90 = (x+3) + (4x-8)
90 = 5x - 5
95 = 5x
/5 /5
19 = x

Therefore the value of x = 19
