Answer:
Diameter = 9
Step-by-step explanation:
Let the diameter be represented as x.
Based on the secant-tangent theorem, the following equation representing the relationship between the segments would be:
(16 + x)(16) = 20²
256 + 16x = 400
Subtract 256 from each side
16x = 400 - 256
16x = 144
Divide both sides by 16
x = 144/16
x = 9
Diameter = 9
I am super mega bored :/ bro
Answer:
can't you just look it up?
Step-by-step explanation:
Answer:
A.
Step-by-step explanation:
if they are similar then you can set up a proportion to solve.
5/x = 7/4
cross multiple to get 20=7x
x=20/7
