Answer 1

Answer:

Therefore 'x' is equal to 65.4°

Step-by-step 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

$\cos C = \dfrac{CB}{AC}=\dfrac{5}{12}$

$\angle C = \cos^{-1}(0.4166)=65.37=65.4\°$

Therefore 'x' is equal to 65.4°
