Answer 1

Answer:

Correct question: In an isosceles triangle the base angles are equal the vertex angle is 40 degree water base angle of the triangle remember the sum of 3 angles of a triangle is 180 degree.

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.
