Question

Can u help me w this i got it incorrect and can’t figure out why

Answer 1

1) We can see here a case in which there are two secant lines coming from a single point over that circle.

2) So, we can write out the following relation

`\begin{gathered} PA\cdot PB=PC\cdot PD \\ 4(4+x)=5(5+7) \\ 16+4x=25+35 \\ 16+4x=60 \\ 16-16+4x=60-16 \\ 4x=44 \\ (4x)/(4)=(44)/(4) \\ x=11 \end{gathered}`
