Question

Solve for xx. Round to the nearest tenth of a degree, if necessary.

Answer 1

x = 52.8°

Explanation:

SOHCAHTOA:

1) SOH: Sine = Opposite over Hypotenuse

2) CAH: Cosine = Adjacent over Hypotenuse

3) TOA: Tangent = Opposite over Adjacent

We can use the cosine function. Cosine is the adjacent side over the hypotenuse, and those are the values given by the figure for the unknown angle, x.

Adjacent = 7.9

Hypotenuse = 15

Cosine(x) = (7.9/15)

Cosine(x) = 0.526667

x = 52.8°

Answer 2

cosx = VU/UW

cosx = 7,9/15

x≈58.219489....=58°
