Question

Find the value of x to the nearest tenth.
х
34°
48

Answer 1

X= 39.79
(39.8 rounded)
Cos= adj/hyp

Answer 2

x ≈ 39.8

Explanation:

cos∅ = adjacent / hypotenuse

Since we are given a right triangle, we can use trigonometry to help us solve for missing values:

cos34° = x/48

x = 48cos34°

x = 39.7938

x ≈ 39.8
