Question 610428
 (1)an isoceles triangle is such that each of the base angle is twice the vertical angle.find the angle of the triangle (2)The angle of a triangle are x, 2x and 3x.find the angles of the triangle
-----
Let the vertex angle has size = "x":
Then each base angle is "2x".
----
Equation:
x + 2x + 2x = 180 degrees
5x = 180
x = 36 degrees (vertex angle)
2x = 72 degrees (each of the base angles)
