Question

Find x to the nearest tenth.

A. 0.7
B. 1.0
C. 1.1
D. 1.4

Answer 1

the answer would be d. 1.4

Answer 2

D

Explanation:

Using the cosine ratio in the right triangle

cos33° =
`(adjacent)/(hypotenuse)` =
`(1.2)/(x)`

Multiply both sides by x

x × cos33° = 1.2 ← divide both sides by cos33°

x =
`(1.2)/(cos33)` ≈ 1.4 ( to the nearest tenth ) → D
