Question

Can someone help me with this question please................

Answer 1

x ≈ 36.2°

Explanation:

Using the sine ratio in the right triangle

sin x =
`(opposite)/(hypotenuse)` =
`(13)/(22)` , thus

x =
`sin^(-1)` (
`(13)/(22)` ) ≈ 36.2° ( to 1 dec. place )

Answer 2

x = 36°

Explanation:

Sine = opposite / hypotenuse

Cosine = adjacent / hypotenuse

Tangent = opposite / adjacent

Sine is viable here since opposite and hypotenuse are given.

sin x = 13 / 22

x = sin⁻¹ (13 / 22)

x = 36.2 ≈ 36
