Answer 2

One angle of a triangle is 60 degree the other two angles are in ratio 5:7. The two angles are 50° and 70°.

Stepwise explanation is given below:

- Measure of one of the angle of a triangle = 60°.

- Other two angles are in the ratio 5:7

- Let the other two angles be 5x and 7x.

- So, we know the sum of the angles of a triangle is 180°.

then, 5x+7x+60° = 180°

12x+60° = 180°

12x = 180° - 60°

12x = 120°

x = 120/12

x = 10°

so, the measure of other two angles will found by putting the value x = 10 is :-

=5x = 5*10 = 50°

And, 7x = 7*10 = 70°

hope it helps of so pls will u mark as brainliest

thanks :D
