Question

In an isosceles triangle, the base angles are equal and the vertex angle is 40°. What are the base angles of the triangle? ​

Answer 1

Answer:

70,70

Step-by-step explanation:

Since the sum of all angels of a triangles =180

Let the base angles be 'x'

Therefore,

x+x+40=180

2x=180-40

2x=140

X= 140/2

x = 70

Hence the base angles of the triangle are 70, 70
