Consider a triangle ABC, and that AA', BB', CC' be the perpendicular form A, B and C upon the sides opposite to them. These three perpendicualrs meets in H, called the orthocenter of the triangle.The triangle `A'B'C'` formed by the feet of the perpendicular is called the pedal triangle of ABC. (Assume `angleA, B, C ne 90^(@)`)

Suppose the triangle ABC have angles `60^(@), 70^(@)` and `50^(@)`. Then the pedal triangle `A'B'C'` have angles given by

Options

A. `80^(@), 60^(@), 40^(@)`
B. `120^(@), 40^(@), 20^(@)`
C. `30^(@), 65^(@), 85^(@)`
D. `45^(@), 55^(@), 80^(@)`
