Question

Each of the two equal angles of a triangle is four times the third angle. Find all the angles of the triangle.
Please show steps as well !!

Answer 1

Let the one of the equal angle of the triangle be X°

so ATQ

x + x + 4x = 180 (using angle sum property)

6x = 180

x = 30°

Hence the angles of the triangle are 30°,30°,120°
