Question

15

67°
X


Find the missing side in the following and round to nearest tenth

Answer 1

Because this is a right triangle, we can use a trigonometric function to solve for the missing side.

Remember: SOH-CAH-TOA

We are given an angle, as well as the adjacent side and hypotenuse. Therefore, we should use the cosine function to solve for x.

cos(67) = x / 15

x = cos(67) * 15

x = 5.9

Answer: 5.9

Hope this helps!
