Question

Find each of the two equal angles of an isosceles triangle whose third angle is 70°.​

Answer 1

Answer:

The equal angles are 55° each

Step-by-step explanation:

Given:-

the two equal angles of an isosceles triangle whose third angle is 70°.

To find:-

Find each of the isosceles triangle .

To find:-

Let the equal angles be X° each

The third angle=70°

We know that the sum of all angles in a triangle =180°

=>X°+X°+70°=180°

=>2X°+70°=180°

=>2X°=180°-70°

=>2X°=110°

=>X°=110°/2

=>X°=55°

Answer:-

The equal angles are 55° each

Answer 2

Answer:

55°

Step-by-step explanation:

Sum of interior angles =180

2 angles are equal

So, let unknown angle = x

Then x+x+70°=180°

2x+70°=180°

2x=180-70

x=110°/2

x=55°
