Question

Find the exterior angle of a triangle if corresponding interior opposite angles are 38' and 42'. * 2 points 80' 70' 60' 50'​

Answer 1

Answer:

sum of the measure of interior opposite angles = the measure of exterior angle

Step-by-step explanation:

Let the no. angle be x

30°+x=110°

x=110°-30°

x=80°

so the other angle is of measure 80°

Now,

The measure of the third angle would be 180-(80+30).

since, sum of all angles of triangles is 180°.

so, here's the solution :-

180-(80+30)

180-110

70°

so the angels measure are as follows

Angle 1:- 30°

Angle 2:-80°

Angle 3:-70°
