Question

the ratio of two angles is 3:1 if the greatest angle is 63 degrees then the smallest angle is

Answer 1

Since it is a ratio, lets introduce a variable "x"

Then, it is given that the greater angle is 63 degrees, in the ratio, the greater number is 3.

Therefore, 63 = 3x , x=21. This is the value of the multiplication to the ratio.

The ratio is 3:1 --> 3x:1x --> 63: 21

Thus, the smaller angle is 21 degrees
