Question

One angle of a triangle is 60 degree.The two angles are in the ratio of 5:7.Find the two angles​

Answer 1

Step-by-step explanation:

let,two angels be x

then,

a/q

1st angle-: 5x

2nd angle :- 7x

3rd angle :- 60

total sum of all three angles :- 180°

then,

5x+7x+60=180

:- 12x =180-60

:- x =120/12

:- x = 10

Then,find angles

1st angle=5x = 5*10= 50°

2nd angle = 7x = 7 *10 = 70°

3rd angle= 60° [given)
