Question
If the ratio of a base angle and vertical angle of an isosceles triangle is 1:2 find the angles of the triangle
Answers

Let the base angle = x
Thus, the vertical angle = 2x
Now, sum of all the angle = 180
or, x + x + 2x = 180
or, 4x = 180
or, x = 45
Thus, angles of the triangle are 45 , 45 , 90
Thus, the vertical angle = 2x
Now, sum of all the angle = 180
or, x + x + 2x = 180
or, 4x = 180
or, x = 45
Thus, angles of the triangle are 45 , 45 , 90
