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 cent

levacccp [35]

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.

In this problem

$(LM)(MK)=(IM)(MJ)$

substitute the given values

$(4)(x)=(16)(7)$

solve for x

$x=16(7)/4\\x=28\ cm$

Remember that

LK goes through the center of the wheel

That means----> LK is a diameter

$LK=4+x\\LK=4+28=32\ cm$

therefore

The diameter of the wheel is 32 centimeters

Answer:

x = -6

Step-by-step explanation:

The three marked angles total 180°, the number of degrees in a semicircle.

(x +51) +65 +70 = 180

x = 180 -186 = -6 . . . . . . . . subtract 186 and simplify

The value of x is -6.
