Question

∠1 and ∠2 are complementary. if m∠1 = (x 3)° and m∠2 = (4x - 8)°. find the value of x. a. 37 b. 19 c. 21 d. 6

Answer 1

b

Explanation:

complementary angles sum to 90° , that is

∠ 1 + ∠ 2 = 90 , then

x + 3 + 4x - 8 = 90

5x - 5 = 90 ( add 5 to both sides )

5x = 95 ( divide both sides by 5 )

x = 19
