Question

Solve for x in the triangle. Round your answer to the nearest tenth.
X
9
64°

Answer 1

Answer:

x = 23.0

Step-by-step explanation:

To solve, you have to make the equation:

$cos(64)=\frac{9}{x}$

Now multiply x to both sides:

$cos(64)*x=9$

Next divide both sides by cos(64):

$x=\frac{9}{cos(64)}$

x = 22.9675486404

Round to the tenth:

x = 23.0
