Solve for x. Round to the nearest tenth.

• 11.1

• 9.3

• 13.0

• 5.5

Answer explanation

$\cos32\degree=\frac{adjacent}{hypotenuse}=\frac{x}{11}$
$11\cdot\cos32\degree=x$
$x\approx9.3$

Solve for x. Round to the nearest tenth.

Make sure your calculator is in DEGREE mode.

• 25.7

• 35.4

• 6.4

• 5.6

Answer explanation

$\tan65\degree=\frac{opposite}{adjacent}=\frac{12}{x}$
Switch $\tan65\degree$ with $x.$
$x=\frac{12}{\tan65\degree}\approx5.6$
