What is the value of x, rounded to the nearest degree?

71

Step-by-step explanation:

You us SOH CAH TOA

In this case you use SOH also called cosine.

This means cos(x)=adjacent/hypotnuse

Now you plug in the numbers

cos(x)=4/12

You put this in your calculator and get

70.5287794

Which then can be rounded to

71 degrees
