Question

In an isosceles triangle, the base angles are equal, the vertex angle is thrice of either the
base angles. What are the degrees major of the angles of the triangle?​

Answer 1

Answer:

36,36,108

Step-by-step explanation:

sum of all angles in a triangle is 180 degrees

Let base angle be x Given , vertex angle is 3x

therefore x+x+3x is 180

i.e., 5x=180

x=36

Answer 2

Answer:

in isosceles 2 sides are equal and angle opposite to those sides are also equal.

Step-by-step explanation:

let those 2 equal angle be x each

so the third angle would be 3x

so, x+x+3x=180( angle sum property of a triangle)

2x+3x=180

5x=180

x=180/5

×=36 degree each

and the third angle is 3x= 3×36= 108 degrees
