Answer:

41.4 degrees

Step-by-step explanation:

Find cos x by dividing both sides of this equation by 4:

cos x = 3/4 = 0.75

Using a calculator's inverse cosine function, find x:

arccos 0.75 = 0.723 radian, or

0.723 rad     180 deg

--------------- * ------------- = 41.4 degrees

        1             pi rad
