Question

An exterior angle of a triangle of measures 80° and one of its opposite interior angle is of measures 30°.Find the measures of other angles of the triangles

Answer 1

exterior angle equal to sum of its two opposite angle.
angle 1 + angle 2 = 80°
30•+ angle 2= 80 angle 2 = 50°

Answer 2

Answer:30,50,100

Step-by-step explanation

Exterior angle=sum of the opposite two interior angles

One opposite interior angle is 30 and exterior angle is 80 so the other must be 50

Also the sum ofexterior angle and corresponding inerior angle is 180 so the other angle must be 100

so all the angles of the triangle are 30, 50 and 100
