Question

3. The measure of one of the base angles of an isosceles triangle is twice the
measure of the vertical angle. Find the measure of the vertical angle.
(1) 30° (2) 36° (3) 40° (4) 48°
​

Answer 1

Answer:

Let vertical angle be x ,

APQ , base angle = 2*vertical angle

So, 2x+2x+x = 180

5x = 180

x = 180/5

= 36

Option 2 is correct
