Question

Find the missing side. Round your answer to the nearest tenth.

Answer 1

x = 19.1

Explanation:

Because this is a right triangle, we can use trigonometry.

Thus, we must use either sine (opposite / hypotenuse), cosine (adjacent / hypotenuse), or tangent (opposite / adjacent).

If we use 33 as the reference angle, the side measuring 16 is the adjacent side and x is the hypotenuse.

Thus, we can use cosine:

`cos 33=(16)/(x) \\x*cos33=16\\x=19.0778=19.1`
