Question

Solve for x in the triangle. Round your answer to the nearest tenth.

13
x =
Х
26°
х

Answer 1

x ≈ 11.7

Explanation:

Using the cosine ratio in the right triangle

cos26° =
`(adjacent)/(hypotenuse)` =
`(x)/(13)` ( multiply both sides by 13 )

13 × cos26° = x , then

x ≈ 11.7 ( to the nearest tenth )
