Question

∠A and \angle B∠B are complementary angles. If m\angle A=(3x+25)^{\circ}∠A=(3x+25) ∘ and m\angle B=(5x-7)^{\circ}∠B=(5x−7) ∘ , then find the measure of \angle A∠A.

Answer 1

m<A = 52

Explanation:

Answer 2

A = 51.375

Explanation:

A = (3x + 24)

B = (5x - 7)

A + B = 90

3x + 24 + 5x - 7 = 90

8x + 17 = 90

8x = 73

x = 9.125

A = (3(9.124) + 24)

A = 51.375
