Subject is Trigonometry. Solve for X.

Answer 1

72.18°

Explanation:

SOHCAHTOA

Sine = Opposite / Hypotenuse

Cosine = Adjacent / Hypotenuse

Tangent = Opposite / Adjacent

There is the opposite side from angle x, which is 28.

And there is the adjacent side, which is 19.

so: tanx = 28 / 19

Solve by using the inverse function on the calculator (usually shift/second and tan button):

`tan^(-1)((28)/(9))=x=72.18111109` degrees
