Question

Can you explain on how you got what you got please? my teacher doesn’t do good on explaining

Answer 1

x = 7

Explanation:

When two secants RT and RP intersect at a point outside the circle, then

`\boxed{\bf RS * RT = RQ * RP}`

RT = 11 + x

RP = 9 + 13 = 22

11 * ( 11 + x) = 9 * 22

`11 + x = (9 * 22)/(11)\\\\11 + x = 9 * 2`

11 + x = 18

x = 18 - 11

x = 7
