Answer 1

Therefore 'x' is equal to 65.4°

Explanation:

In Right Angle Triangle ABC

∠ B = 90°

AC = Hypotenuse = 12

CB = Adjacent Side = 5

To Find:

∠ C = x

Solution:

In Right Angle Triangle ABC Cosine Identity we have

`\cos C = \frac{\textrm{side adjacent to angle C}}{Hypotenuse}\\`

Substituting the values we get

`\cos C = (CB)/(AC)=(5)/(12)`

`\angle C = \cos^(-1)(0.4166)=65.37=65.4\°`

Therefore 'x' is equal to 65.4°
