Question

The two interior opposite angles of an exterior angle of a.triangle LMN are 60 degree and 80 degree find the measure of the exterior Angle​

Answer 1

Answer:

140°

Step-by-step explanation:

Firstly find the sum of angles = 60° + 80° = 140°

Therefore, angle MLN = 180°- 140°= 40°

Now exterior angle MLN = 180°-40° = 140° ans....
