Answer 1

Correct Question :-

If two angles of triangle are 30 ° and 40°, then find the measure of the third angles of the Triangle.

Answer :-

Third angle is 110°.

Given :-

Two angles of a triangle which are 30° and 40°.

To find :-

The third angle of the triangle.

Solution :-

We will find the third angle of the triangle with the help of angle sum property.

Angle sum property is described as,

The sum of all the angles of a triangle is equal to 180°.

A + B + C = 180°

A is first angle of the triangle

B is second angle of the triangle

C is third angle of the triangle

So, Let take 30° as angle A and 40° as angle B. Then, we have to find third angle which is C.

Applying angle sum property,

=> 30° + 40° + C = 180°

=> 70° + C = 180°

=> C = 180° - 70°

=> C = 110°
