Step-by-step explanation:
From the given right angle triangle,
The unknown side represents the hypotenuse of the right angle triangle.
With m∠40 as the reference angle,
x represents the adjacent side of the right angle triangle.
4 represents the opposite side of the right angle triangle.
To determine x, we would apply
the Tangent trigonometric ratio.
Sin θ = opposite side/hypotenuse. Therefore,
Tan 40 = 4/x
x = 4/Tan 40 = 4/0.839
x = 4.8
Step-by-step explanation:
Since y varies directly with x,
y = kx, where k is a real constant.
When x = 4, y = 32.
=> (32) = (4)k, k = 8.
Therefore when x = -2,
y = kx = (8)(-2) = -16.
