15 degrees because its basically dividing 60 divided by 4 is 15
Sum of angles in a triangle is 180°
.
Since we know that angle A = 60,
Therefore angle B + angle C = 180 - 60 = 120°
.
Define x:
Let angle c be x.
angle b = 1/4 x
.
Solve x:
x + 1/4 x = 120
5/4 x = 120
5x = 480
x = 96
.
Find angle c:
angle c = x = 96°
.
Answer: Angle C = 96°
