Question

In an isosceles triangle if the vertex angle is 7 0 degrees find the base angles
​

Answer 1

Answer:

Step-by-step explanation:

Let base angles of isosceles triangle is x

Sum of all angles of traingle = 180

X + X + 70 = 180

2x = 110

X= 55 Answer

Answer 2

Answer:

55°,55°

Step-by-step explanation:

An isosceles triangle has its base angles equal.

So, let both base angles be x,x

Vertex angle=70°

x + x+70° = 180° (Angle sum property of triangle)

2x = 180 -70°

2x = 110°

x= 110÷2

x=55°

The base angles are 55°,55°
