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:

x ≈ 29.1

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos31° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{x}{34}[/tex] ( multiply both sides by 34 )

34 × cos31° = x , then

x ≈ 29.1 ( to the nearest tenth )
