Question

Anyone know the answer please

Answer 1

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 2

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
