Answer:

a. AB = 3.4 ft

b. AE = 1.6 ft

Step-by-step explanation:

SOH CAH TOA reminds you of the relationship between trig functions and right triangle sides.

a. Cos = Adjacent/Hypotenuse

cos(28°) = BE/BA = 3 ft/BA

Multiplying by BA and dividing by cos(28°), you get ...

BA = (3 ft)/cos(28°) ≈ 3.4 ft

___

b. Tan = Opposite/Adjacent

tan(28°) = AE/BE = AE/(3 ft)

Multiplying by 3 ft, you get ...

AE = (3 ft)·tan(28°) ≈ 1.6 ft
