Question

7. If an exterior angle of a triangle is 1150 and one of the interior opposite angles is 600. Find the other two angles of a triangle.​

Answer 1

Answer:

Need to determine other interior opposite angle . Here we eill be using following theorem which says that "sum of two interior opposite ...

Answer 2

Answer:

We know exterior angle of a triangle = sum of the two interior opposite angles

So here given

exterior angle = 115 degree

and one interior opposite angle = 60 degree

So the other interior opposite angle is

= 115 - 60

= 55 degree

Now two angles of the given triangle are 60 and 55 degree

Ww know

Sum of all the three interior angles of triangle is 180 degree

So

55 + 60 + third angle = 180

115 + third angle = 180

third angle = 180 - 115

third angle = 65 degree

So the three angles of the given triangle are

55 degree, 60 degree and 65 degree.

I hope it will help you.
