Please help!!! Intersection of chords use formula a•b=c•d
scoray [572]

Given:

Length of chords of one segment = 11 and 8

Length of chords of other segment = 2 and x

To find:

The value of x.

Solution:

<em>If two chords intersect each other inside a circle, the products of length their segments are equal.</em>

\Rightarrow a \cdot b =c \cdot d

\Rightarrow 11 \cdot 8 =2 \cdot x

\Rightarrow 88 =2x

Divide by 2 on both sides.

$\Rightarrow\frac{88}{2} =\frac{2x}{2}

$\Rightarrow 44 =x

Switch the sides.

$\Rightarrow x=44

The value of x is 44.

I appreciate any help. Trying to get the hang of these.
aliya0001 [1]

Answer:

x = 12

Step-by-step explanation:

Since the top line is equal to the bottom, you make the equation -

x + x + 4 = x + 16

You subtract an x on both sides because there is one on each side -

x + 4 = 16

Then you subtract the 4 from both sides to get x by its self, which makes

x = 12
