Question

If one angle of a triangle is 80° and the other 2 angles are in the ratio 3:7

Answer 1

Answer:

Let the constant be n.

According to the given condition.

3n+7n+80=180

10n=180-80

10n=100

n=100/10

n=10

Hence, other two angles are of 30° and 70°.

Answer 2

Answer:

Let ratio be x

=>3x+7x+80 = 180

=> 10x = 100

=>x = 10
