If ∠a, and ∠b, are complementary angles and if m∠a =4x-8 and∠b =2x + 2, what is value of x?

"Complementary angles" means that sum of the angles = 90⁰.

m∠A  +m∠B = 90⁰

(4x-8) + (2x +2) = 90⁰

6x - 6 = 90

2x - 2 = 30

2x = 32

x = 16

typically if you want , you would actually put questions here for us to you. but hey, that's just me. maybe someone will magically answer the questions for you without knowing what they are.

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
