Answer:

11.5 units

Step-by-step explanation:

Since the radius is perpendicular to the tangent C, BC is perpendicular to AB

So using the Pythagorean Theorem,

x^2 = (9 + x)^2 - 15^2

x^2 = 81 + 18x + x^2 - 225

18x = 225 - 18

= 207/18

= 11.5 units

Hope this helps, and please mark me brainliest if it does!

Answer:

As radius is perpendicular to tanget ,

BC is perpendicular to AB

By pythagoras theorem:

x² = (9 + x)² - 15²

x² = 81 + 18x + x² - 225

18x = 225 - 18

x = 207/18 = 11.5

You get tired of the sand and head up to the amusement park. You can purchase 20 ride tickets for $14 or you can purchase 30 rid

Helga [31]

Answer:

The one with the better deal would be 30 ride tickets for $22.50 this is because you pay less money for more rides.

Step-by-step explanation:

First you divide 20 by 14. Doing this will give you the cost of a ride per ticket.

20/14 = 1.42

Then you do the same thing to 30 and 22.50.

30/22.50 = 1.30

Last you compare which deal has less money per ride.

1.42 > 1.30
