Question

Find the missing side. Round to the nearest tenth.

a. 3.4
b. 36.0
c. 38.6
d. 41.2

Answer 1

tan(angle) = opposite/adjacent

tan(17) = 11/x

x*tan(17) = 11 .... multiply both sides by x

x = 11/tan(17) ...... divide both sides by tan(17)

x = 35.9793788 .... use your calculator

x = 36.0

Answer: Choice B) 36.0
