What is the measure of ∠f, to the nearest degree? 44° 57° 71° 78°

A.

Step-by-step explanation:

We have been given a triangle FGH, we are asked to find the measure of angle F.

We will use law of cosines to solve our given problem.

, where, a, b and c are sides of triangle and C is the angle opposite to side c.

Upon substituting our given values in above formula we will get,

Now we will use arccos to solve for measure of angle F.

Therefore, the measure of angle F is 44 degrees and option A is the correct choice.
