Question

Find the missing side. Round to the nearest tenth.
52°
27

Answer 1

`( \cos(52) )/(1) = (x)/(27)`

Cross multiply!

`x = 27 \cos(52)`

Determine by using a calculator!

Answer: x is approximately 16.6

Answer 2

x = 16.6

Explanation:

Use Cos

Cos 52 = x / 27

Cos of 52 is 0.61566

0.61566 = x / 27

Multiply 27 on both sides

16.622 = x

Round to the nearest tenth

16.622 = 16.6
