Question

Which of the following is the correct value for x?

Answer 1

Answer: 56

Step-by-step explanation:

Answer 2

Answer:

x = 55.94 degrees

Step-by-step explanation:

(to find x, use cosine) (cos = $\frac{adjacent}{hypothenuse}$)

First step: write out the equation

⇒ cos x = $\frac{14}{25}$

Second step: find out what $\frac{14}{25}$  is

⇒ $\frac{14}{25}$ = 0.56

Third step: find out what the cos-1 of 0.56 is

⇒ cos-1 of 0.56 = 55.94

Fourth step: you got your answer

⇒ x = 55.94
