Question

in an isosceles triangle the vertex angle is thrice of either base angle.find the measure of base angle

Answer 1

Answer:

Step-by-step explanation:

Let base angle be x for now

If each base angle = x then vertex angle = 3x

Sum of all angles = 180 degrees

x  +  x  +  3x = 180 degrees

5x = 180 degrees

x = 180/5

  = 36 degrees

x = 36 degrees

3x = 3 x 36

    = 108 degrees

Angles of the triangle are - 36, 36 and 108 degrees.
