Question

Q2. An exterior angle of a triangle is 110° and one of the interior opposite
angle is 30°. Find the other two angles of the triangle.
O 80°, 30°
O 70°,80°
O 70°,180
O 100°,100​

Answer 1

Answer:We know that,

Sum of the measures of the interior opposite angles= The measure of exterior angle.

So,

Let the unknown 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 the angles of a triangle is 180°.

So here's the solution:

180-(80+30)

180-110

70°

So the angles measures are as follows:

Angle 1: 30°

Angle 2: 80°

Angle 3: 70°
