Question

In an isosceles triangles,the base angles are equal.the vertex angle is 80°.what are the base angle of the triangle?

Answer 1

Answer:

50 degree each

Answer 2

In an isosceles triangle the base angles are equal
Base angle be ‘x’
Since there are two base angles then it become 2x
The vertex angle is 80 degrees
2x+80=180 (Angle sum property)
2x= 180- 80
2x = 100
X= 100 / 2
X= 50 degrees
Therefore the angles are 80, 50, 50.
