Question

Find value of X. Round to the nearest tenth. right Triangle 36° , 10, x

●Problem #8 ​

Answer 1

x ≈ 8.1

Explanation:

using the cosine ratio in the right triangle

cos36° =
`(adjacent)/(hypotenuse)` =
`(x)/(10)` ( multiply both sides by 10 )

10 × cos36° = x , then

x ≈ 8.1 ( to the nearest tenth )
