Question

the vertical angle of an isosceles triangle is twice the sum of its base angles find each angles of the triangle

Answer 1

Answer:

Step-by-step explanation:

let base angles be a and b and vertical angle be c

let a = x so b = x (since base angles of isosceles triangle are equal)

then, c = 2 (x+x) = 4x

now,

x+x+4x = 180(sum of all angles of triangle is 180)

6x = 180

x = 30

hence, each angle is 30.
