Question

Use the theorems to find x in the following circles.
x = please help

Answer 1

click good answer if I desever

Answer 2

its not right

Answer 3

what is the key?

Answer 4

x=3+9
=12

Answer 5

If a tangent segment and a secant segment intersect outside a circle, then the square of the measure of the tangent segment equals the product of the measures of the secant segment and its external portion.

=> 6^2=3*x
36=3x
36/3 = x
12 = x

Answer 6

I positive I correct

Answer 7

see my solution, that is the correct application of the theorem i mentioned...

Answer 8

sorry give y frist
and y+x=9+3=12

Answer 9

Use the theorems to find x in the following circles.
x =

Answer 10

i forgot give y indtate x
solve y =9
y+3=x
x=9+3
x=12 my answer it correct

Answer 11

pls see the wording of the theorem " product of the measures of the secant segment and its external portion."
here secant segment is = x
external portion = 3
so their product is 3*x

Answer 12

4*3 = 2*x
12/2 = x
6 = x

Answer 13

2x=4*3

Answer 14

x=6

Answer 15

6^2=3(3+y)
36=3(3+y)
36=9+3y
3y= 36-9
y= 27/3
y =9
x=9+3
x=12

Answer 16

I missup y=x

Answer 17

no problem ☺

but if full secant and its outer segment are given, then my method is direct and easier...
