Question

Solve for x in this triangle. Round your answer to the nearest tenth. 13 35⁰ X​

Answer 1

x ≈ 10.6

Explanation:

using the cosine ratio in the right triangle

cos35°=
`(adjacent)/(hypotenuse)` =
`(x)/(13)` ( multiply both sides by 13 )

13 × cos35° = x , then

x ≈ 10.6 ( to the nearest tenth )
