Question

What is the m∠ F?

(Just type the number - without degrees)

Answer 1

All degrees (angles) in a triangle add up to 180°. So we can set the sum of the three angles equal to 180°:
(x-5)+(3x+25)+x = 180
5x + 20 = 180
5x = 160
x = 32°
But it asked for m<F, so plug in for x:
m<F = x - 5 = 32 - 5 = 27°

Answer 2

The answer is 27 for angle f
