Question

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

Answer 1

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

`\sqrt{20 ^(2) } - 5^(2)`

=19.36

20
