Question

In an isosceles triangle, the base angles are equal and the vertex angles is 70. What are the base angles of the triangle​

Answer 1

Answer:

hope it's helpful to u.Thank u

Answer 2

Answer:

55°

Step-by-step explanation:

Let, one base angle is x. Anotber one will also be x because the two angles are equal.

We know, the sum of three angles of a triangle is 180°.

Given, vertex angle is 70°.

According to the question,

x + x + 70 = 180

=> 2x + 70 = 180

=> 2x = 180 - 70

=> 2x = 110

=> x = 110÷2

=> x = 55

Therefore, two base angles are both 55°
