Question

3 angles which add up to 180 degree are in the ration 2: 3: 7. find them

Answer 1

Let the angles are 2x:3x:7x now. 2x+3x+7x=180degree, 12x=180 ,x= 180÷12=15. now,15×2=30degree ,3×15=45degree,15×7=105degree.I hope it will help you and mark me as a brain list.

Answer 2

let's take angle as 2x 3x & 7x
then,
2x+3x+7x=180
12x=180
therefore x=180/12
=15
now substitute value of x in angles 2x 3x 7x
now,
2x=2×15
=30
3x=3×15
=45
7x=7×15
=105
therefore 3angles are 30,45,105
