Answer:

Step-by-step explanation:

From the given right angle triangle,

The unknown side is the hypotenuse of the right angle triangle.

With m∠x as the reference angle,

The adjacent side of the right angle triangle is 10

The opposite side of the right angle triangle is 20

To determine m∠x, we would apply

the tangent trigonometric ratio.

Tan θ, = opposite side/adjacent side. Therefore,

Tan x = 20/10 = 2

x = Tan^-1(2)

x = 63.4° to the nearest tenth.
