If AS = 20 and BS = 5, what is the measure of AC? Round to the nearest hundredth. Show all your work.

Answer:
When a radius and a tangent meet it us always 90 degrees therefore as is the hypotenuse and the length of a radius in a circle stays constant finding ac is easy as you use pythagoras theorem
C2-a2=b2
[tex] \sqrt{20 ^{2} } - 5^{2} [/tex]
=19.36
20
