Question

the measure of two angles of a triangle are given in the following table. measure of third angle (a) 30degree, 80degree(b) 25degree, 55degree​

Answer 1

Answer:

The Third angle of the triangle is 125°

Given :

The 2 angles = 30° and 25°

To find :

The measure of the third Angle

Solution :

By using the Angle sum property of triangle we can find the third angle.

Angle sum property :

This property of triangle states that all angles of triangle sum up and make 180°

Consider the thjrd angle as x

The Third angle of the triangle is 125°

When we placed the value of x (125) we got the required answer 180°

The Third angle of the triangle is 125°
