Question

4. One of the exterior angles of triangle is 100°. The interior opposite angles are equal to
each other. Find the measure of these equal interior opposite angles. 50° soo
angle is 75​

Answer 1

Answer:

the measure of equal opposite interior angle is 50 degree

Answer 2

Answer:

let one angle be x

then it opposite angle is also x

and x + x = 100       [exterior angle property]

  2x = 100

x = 100/2

x = 50 degree

so both interior angle which is opposite to one another is 50 degree

50 + 50 + 3 rd angle = 180    [ sum of all angles of triangle]

100 + 3rd angle = 180

3rd angle = 180 - 100

3rd angle = 80 degree
