Find the value of x and round answer to nearest tenth.

Step-by-step explanation:

From the given right angle triangle,

The hypotenuse of the right angle triangle is 21

With m∠x as the reference angle,

The unknown side represents the adjacent side of the right angle triangle.

The opposite side of the right angle triangle is 10

To determine m∠x, we would apply

the Sine trigonometric ratio.

Sin θ = opposite side/hypotenuse. Therefore,

Sin x = 10/21 = 0.4762

x = Sin^-1(0.4762)

x = 28.4° to the nearest tenth.
