Question

In traiangle measure of two angles are equal and third angle is 400. What are the measure of the equal angles?​

Answer 1

Answer:

Step-by-step explanation:

sum of interior angles of triangle is only 180°,so it is not possible that one angle is400°

Answer 2

Correct Question :

›»› In triangle measure of two angles are equal and third angle is 40°. What are the measure of the equal angles?

Answer :

›»› The measure of the equal angles is 70°.

Given :

• In triangle measure of two angles are equal and third angle is 40°.

To Find :

• The measure of the equal angels.

Solution :

Let us assume that, the measure of the equals angles us "x"

As we know that

The sum of all three angles of a triangle is 180°.

This is also known as angle sum property of triangle.

→ x + x + 40 = 180

→ 2x + 40 = 180

→ 2x = 180 - 40

→ 2x = 140

→ x = 140/2

→ x = 70

Therefore,

The measure of the equals angle of a triangle will be,

• x = 70°.

Hence, the measure of the equal angles is 70°.

Verification :

The sum of all three angles of a triangle is 180°.

→ x + x + 40 = 180

→ 70 + 70 + 40 = 180

→ 140 + 40 = 180

→ 180 = 180

Here, L.H.S. = R.H.S.

Hence Verified !
