Question

The exterior angle of a triangle and one interior opposite angles have a ratio 10:3 . if the measure of the other interior opposite angle is 70 degree ,find all the remaining angles​

Answer 1

Answer:

Step-by-step explanation:

Let the exterior angle be 10 X ,

10x =3x +70. (exterior angle is equal to its opposite interior angle)

By solving equation,

10x-3x=70

7x=70

X=10

So ,

Exterior angle=10x=(10×10)=100

Interior angle=3x=(3×10)=30
