Answer: x = 16.9
Concept:
Here, we need to know the idea of basic trigonometry.
Sine = Opposite / Hypotenues = O / H
Cosine = Adjacent / Hypotenues = A / H
Tangent = Opposite / Adjacent = O / A
Solve:
Angle θ = 50°
Opposite = x
Hypotenues = 22
Given formula
Sine = Opposite / Hypotenues
Substitute the value into the formula
sin (50) = x / 22
Multiply 22 on both sides
sin (50) × 22 = x/22 × 22
x = 22 sin (50)
x = 16.9
Hope this helps!! :)
