Question

in an isosceles triangle, the vertex angle is 50 degree what are the bases of triangle

Answer 1

Answer:

let the base angle be x.

then using angle sum property

x+x+50°=180°

2x=180°-50°

2x=130°

x=65°

The base angles are 65 degree

Answer 2

Answer:

The bases of triangle is 65 degree

Step-by-step explanation:

<A+<B+<c=180°

Since, <A=50° and In isoceles triangle <B = <c

Therefore 2<B = 180-50°

<B = 130/2

<B = 65°

So, bases of triangle has the angle of 65°
