Question

The eguial angles of a traingle are of measure 70 each measure of third angle

Answer 1

Answer:

Given -

• Measure of two equal angles of triangle = 70°

To find -

• Measure of third angle.

Solution -

Let the third angle be z.

As we know that the sum of all angles of triangle is 180°.

Then,

70 + 70 + z = 180°

→ 140 + z = 180°

→ z = 180° - 140°

→ z = 40° .

Therefore, the measure of third angle is 40°.

Answer 2

Given :-

• The measure of two equal Angles of a triangle = 70°

To FinD :-

• The measure of third angle.

Solution :-

Let, the third angle is x

• We know that The sum of all angles of a triangle is 180°.

So,

70 + 70 + x = 180

140 + x = 180

x = 180 - 140

$\boxed{x = 40° }$

So, the measure of third angle of triangle is 40°.
