Answer:
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.
