The vertical angle is 72°
Step-by-step explanation:
It has been given that
Base angle = 54 °
Now, we know that in an isosceles triangle, the base angles are equal.
Thus, the two angles of the triangle is 54 °
Let the vertical angle is x
In a triangle, the sum of interior angles is 180°. Therefore, we have
x + 54 + 54 = 180
x + 108 = 180
x = 180 - 108
x = 72°
Therefore, the vertical angle is 72°
