​

Answer 1

Answer:

The Exterior angle of the triangle is equal to the sum of its interior opposite angles. and the two opposite angles are equal. so it will be 50° and 50°.

Answer 2

Answer:

40 degree each angle

Step-by-step explanation:

angle of triangle=180 degree

a+b+c=180 degree

a=100

b=c(given )

100+b+c=180 degree

b+c=180-100

b+c=80

40+40=80

interior angle=40 degree and 40 degree
