Question

In given figure if $AC,BC$ and $AB$ are tangents to circle at $Q,R$ and $P$ respectively. $AP=x,BR=y,CQ=z$ Find $AQ$.

• A. $x$
• B. $y$
• C. $z$
• D. $x+z$

Answer 1

The correct option is A $x$

In given figure

$AQ=AP$ ($\therefore$ Tangents from external point are equal in length)

$\therefore AQ=x$
