Question 1026337: A line is drawn perpendicular to the base of an equilateral triangle at one of the vertices of a triangle. Find the number of degrees in the angle made by the perpendicular and the other side of the triangle that contains this vertex.
A. 30 B. 45 C. 60 D. 90
Totally lost on this one. Answer by rothauserc(4718) (Show Source):
You can put this solution on YOUR website! Each interior angle of an equilateral triangle is 60 degrees.
:
A perpendicular line from the base to the opposite interior angle bisects that angle.
:
Therefore, the answer is A. 30 degrees
