In the circle, CP=x and PD=y. If xy=28 and AP=2, then what is PB?

1 answer:

5 0

We know that
<span>When two chords intersect each other inside a circle, the products of their segments are equal
</span>
so
CP*PD=AP*PB
x*y=2*PB-----------> 28=2*PB----------> PB=14

the answer is
PB=14

Marta_Voda [28]

Let the side of each side of photo is a inch.

So area of photo = (side)^2 = $a^2$

But as given area of photo is 9 square inch.

So $a^2 = 9$

$a = \sqrt{9}$
$= 3$

So side of photo is 3 inch.
