In the figure below, ac is tangent to circle b. ba is a radius of circle b and a is a point of tangency. if ab is equal to 15 and bc is equal to 50, what is the approximate measure of segment ac? imported asset question 10 options: 47.1 47.3 47.5 47.7

Using the pythagorean theorem
Base×Base + Perpendicular×Perpendicular = Hypotenuse× Hypotenuse
or B^2+P^2=H^2
B=root H^2 -P^2
Here hypotenuse =50 and Perpendicular = 15
therefore
root(50×50-15×15)
=root(2500-225)
=root(2275)
=47.69
=47.7 (approximately)
Option D is your answer.
