Answer:
Step-by-step explanation:
From the given right angle triangle,
The unknown side represents the hypotenuse of the right angle triangle.
With m∠x as the reference angle,
the adjacent side of the right angle triangle is 7.8
the opposite side of the right angle triangle is 8
To determine m∠x, we would apply
the Tangent trigonometric ratio.
Tan θ, = opposite side/adjacent side. Therefore,
Tan x = 8/7.8 = 1.026
x = Tan^-1(1.026)
x = 45.7° to the nearest tenth
