Question

Find the value of x.

Answer 1

Answer:

70.86 degrees

Step-by-step explanation:

cos x = adjacent side / hypotenuse

= 2/6.1 = 0.32787

x = 70.86.

Answer 2

Answer:

x ≈ 70.9°

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos x = $\frac{adjacent}{hypotenuse}$ = $\frac{2}{6.1}$ , then

x = $cos^{-1}$ ($\frac{2}{6.1}$ ) ≈ 70.9° ( to 1 dec. place )
