Question

Find the value of x.

Answer 1

x ≈ 70.9°

Explanation:

Using the cosine ratio in the right triangle

cos x =
`(adjacent)/(hypotenuse)` =
`(2)/(6.1)` , then

x =
`cos^(-1)` (
`(2)/(6.1)` ) ≈ 70.9° ( to 1 dec. place )

Answer 2

70.86 degrees

Explanation:

cos x = adjacent side / hypotenuse

= 2/6.1 = 0.32787

x = 70.86.
