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

Substituting the values we get

Therefore 'x' is equal to 65.4°

answer: all the values are within because it has a pattern that repeats from -6 to 4.
