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

a. 12.5 kg

step-by-step explanation:

f = ma

so

m = f/a = (2500 n)/(200 m/s²) = 12.5 kg

1 n = 1 kg·m/s²
