Question

. 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.​

Answer 1

Answer:

50° is the correct answer.

Step-by-step explanation:

Exterior angle=100°

Sum of internal opposite angles=100°

Both are equal, so le the angles be x and x.

x + x = 100°

=>2x = 100°

=>x = 100°/2

=>x = 50°

Please mark me as the brainliest answer.

Answer 2

Answer:

exterior angle of a ∆ = sum of interior opposite angles

given : exterior angle say x = 100°

to find interior opposite angles say y and z

=> y = z [ given] ...........1

=> x = y + z

=> x = 2y [ from equation 1 ]

=> 100 = 2y

=> y = 100/2

=> y = 50°

therefore x = y = 50°

each of interior opposite angles are 50° each
