Question

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

Answer 1

Khushi here☺️

we know that the sum of angles in a triangle is 180

now let us consider the angles in ratio to be 5\times x\ \ and\ 7\times x5×x and 7×x

so,\ 5\times x+7x+60=180so, 5×x+7x+60=180

12\times x=180-60=12012×x=180−60=120

x = 10

Therefore the angles will be 5\times x=5\times10=50\ and\ 7\times x=7\times10=705×x=5×10=50 and 7×x=7×10=70

Answer 2

Step-by-step explanation:

taking ratio's as 5x and 7x

Using angle sum property

5x+7x+60=180

12x=180-60

12x=120

x=10

Therefore 5x=5(10)=50

7x=7(10)=70
