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

maximum area = xy = (16)(32) = 512 ft2

to maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.'
