\angle A∠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

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
