Question

Find the value(s) of the variable(s). If necessary, round decimal answers to the

nearest tenth.
X
4
35°

Answer 1

x = 5.7

Explanation:

Since this is a right triangle, we can use trig functions

tan theta = opp side/ adj side

tan 35 = 4/x

Multiply each side by x

x tan 35 = 4

Divide each side by tan 35

x = 4/ tan 35

x=5.71259

Rounding to the nearest tenth

x = 5.7
