Question

Solve for x. (round to the nearest tenth)

Answer 1

If a triangle equals 180 that means 34+31=65 then subtract that from 180 so you do 180-65=115 and then that means 115 is your answer

Answer 2

x ≈ 29.1

Explanation:

Using the cosine ratio in the right triangle

cos31° =
`(adjacent)/(hypotenuse)` =
`(x)/(34)` ( multiply both sides by 34 )

34 × cos31° = x , then

x ≈ 29.1 ( to the nearest tenth )
