Question

Three angles which add upto 180* are in the ratio 2:3:7. Find them

Answer 1

let one angle be 2x
other = 3x
third = 7x
a. t .p
2x+ 3x+ 7x = 180
12x = 180
x= 15
2x= 2x 15 = 30
3x = 3x 15=45
7x = 7x 15 = 105

Answer 2

Here is the answer
Given 2:3:7= 180
2x+3x+7x= 180
12x =180
x= 180/12. So angle A = 2*15=30
X= 15 angle B= 3*15= 45
Angle C =7*15=105
