Question

An exterior angle of triangle is 100 degree and it's interior opposite angles are equal to each other.Find the measure of each angle of the triangle​​​

Answer 1

Answer:

exterior angle = sum of two opposite interior angle.

100degree = sum of two opposite interior angle.

both opposite interior angle are equal( given )

two opposite interior angle are =100/2=50 degree

sum of all angle of triangle =180degree

sum of two opposite interior angle =50+50=100degree

third angle =180-100=80 degree

Step-by-step explanation:

measure of each angle =50, 50 and 80

Answer 2

Answer:

50°, 50° and 80°

Step-by-step explanation:

Exterior angle is equal to measure of it opposite interior angles.

opposite interior angles are equal, so measure of each one is 100/2 = 50°

sum of all angles = 90°

∵ sum of two of the angles = 50° + 50° = 100°

∴ measure of third angle = 180- 100 = 80°

so, the three angles of the triangle are-

50°, 50° and 80°
