Use photo math!!! it helps a lot!
A.) the 15th day, because you would the less common multiple is 15 of 3 and 5.
∠FEG is an exterior angle.
An exterior angle of a triangle is equal to the sum of the opposite interior angles, so
2x + x = x + 40
3x = x + 40
3x - x = 40
2x = 40
x = 20
m∠FEG = x+40 = 20+40 = 60°
43.8 + x = 46.59
x = 46.59 - 43.8 ( when you move a number to the other side, flip the sign)
x = 2.79 (answer)
hope this helps
