Question

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

Answer 1

x° = 55.7°

Explanation:

I used cosine function because the two sides that were given where hypotenuse and adjacent.

cos(x°) = adjacent/hypotenuse

cos(x°) = 5.3/9.4

cos(x°) = 0.5638

x° = cos-1 0.5638

x° = 55.7°

Answer 2

x = 55.7

Explanation:

Put your calculator in degree mode.

`\cos(x) = (5.3)/(9.4)`

`x = { \cos }^( - 1) (53)/(94) = 55.7`
