What is m∠A?

Enter your answer in the box.

60 degrees

Step-by-step explanation:

sum of interior angles in a triangle is always 180 degrees

find m<E from triangle CED: 43 + m<E + 35 = 180 degrees

m<E = 102 degrees

find m<A: 102 + m<A + 18 = 180

m<A = 60 degrees

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.'
