Isn’t it that famous 5,12,13 triangle? If it is then x=5.

Answer:

x ≈ 4.4

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos70° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{x}{13}[/tex] ( multiply both sides by 13 )

13 × cos70° = x , then

x ≈ 4.4 ( to the nearest tenth )
