Question

Write TWO different equations that you could use to solve for x. You don't need to solve.

Answer 1

see explanation

Explanation:

Using the cosine ratio in the right triangle

cos52° =
`(adjacent)/(hypotenuse)` =
`(18)/(x)` → (1)

The 3rd angle in the triangle is

180° - (90 + 52)° = 180° - 142° = 38°

Using the sine ratio in the right triangle

sin38° =
`(opposite)/(hypotenuse)` =
`(18)/(x)` → (2)
