Question

In an issoselss triangle the base angles are equal and the vertex angle is 40°then what are the base angles of the traingle

Answer 1

Answer:

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

Step-by-step explanation:

Answer 2

Answer:

let the base angle be x

then

by angle sum property of triangle,

x + x + 40 = 180

2x = 140

x = 70

Base angles are 70 and 70
