Question

The vertical angle of an isosceles triangle is 70

. Find measurement of its base angles​

Answer 1

Answer:

55°

Step-by-step explanation: We know that,

In an isosceles  triangle base angles are equal,

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

Given that vertical angle is 70°, the remaining angles, will be 180° - 70° = 110°

As the base angles are equal  each base angle  will be 110°/2 = 55°

Answer 2

vertical angle is 70°

the two base angles will be equal say x

x + x + 70 = 180

2x + 70 = 180

2x = 180 - 70

2x = 110

x = 110/2

x = 55°

so each base angle is 55°
