Question

Can I get help with this?

Answer 1

Around 13.7

Explanation:

The cosine of an angle in a right triangle is equivalent to the length of the adjacent side divided by the length of the hypotenuse. In this case, this means:

`\cos 70= (x)/(40) \\\\x=40\cdot \cos 70\approx 13.7`

Hope this helps!
