Question

15.In an Isosceles triangle the vertex angle is twice either base angles.If base angle is x˚.Find the Sum of angle of triangle using x​

Answer 1

Answer:

90 degree- Vertex angle and 45 degree- each base angles

Step-by-step explanation:

Let the base angles be x. So the vertex angle= 2x

2x+x+x=180 (Angle sum property)

4x=180

x=180/4

x=45

So base angles are= x= 45 degrees

and vertex angle=2x=90 degrees
