We can use the trigonometric function cosine to find the value of x.
cos(72°) = adjacent/hypotenuse
We want to solve for the length of the adjacent side, which is x in this case.
cos(72°) = x/16
To isolate x, we can cross-multiply:
x = 16*cos(72°)
Using a calculator, we get:
x ≈ 4.9
Therefore, the value of x to the nearest tenth is 4.9.
Find the value of x to the nearest tenth.
hypotenuse: 16
angle a: 72°
show work.
