Question

in an isosceles triangle,the vertical angle is 40°. find the other two angles of a triangle.​

Answer 1

The other two angles, Each measure 70°

Let x be the other two angles ( As we know base angles of an isosceles triangle are equal )

So,

x + x + 40° = 180° ( Sum three angles of a triangle equals 180° )

→ 2x + 40° = 180°

→ 2x = 180° – 40°

→ 2x = 140°

→ x = 140° ÷ 2

→ x = 70°

Answer 2

Step-by-step explanation:

Isosceles triangle is a triangle whose 2 pair of sides are equal. So, x+x+40=180°(Sum of all angles of a triangle)

=>2x+40=180

=>2x =180-40=140

=>x =140/2

=> x 70

Therefore,the answer is 70 respectively.
