A bike wheel is shown. Chords I J and L K intersect at point M. The length of I M is 16 centimeters, the length of M J is 7 centimeters, the length of L M is 4 centimeters, and the length of M K is x. LK goes through the center of the wheel pictured. Find the diameter of the wheel. Use the intersecting chords theorem to write the equation . The diameter of the wheel is .


The first drop down is 4x=(7)(16)
The second drop down is 32

Answer:

The diameter of the wheel is 32 centimeters

Step-by-step explanation:

we know that

The intersecting chords theorem states that the products of the lengths of the line segments on each chord are equal.

so

In this problem

[tex](LM)(MK)=(IM)(MJ)[/tex]

substitute the given values

[tex](4)(x)=(16)(7)[/tex]

solve for x

[tex]x=16(7)/4\\x=28\ cm[/tex]

Remember that

LK goes through the center of the wheel

That means----> LK is a diameter

[tex]LK=4+x\\LK=4+28=32\ cm[/tex]

therefore

The diameter of the wheel is 32 centimeters
