Find length jm in the image attached.

12

Step-by-step explanation:

I find it convenient to use the following relation:

JL -KL +5 = JM

(x +7) -(2x -4) +5 = 3x . . . . . substituting values shown

16 -x = 3x . . . . . . . . . . . . . . . collect terms

16 = 4x . . . . . add x

4 = x . . . . . . . divide by 4

JM = 3x = 3·4 . . . . . . find the length of JM

JM = 12

answer;

the correct answer

just use google you beautiful person.

have a nice day < 3

“ a line segment that has the endpoints on the circle and passes through the midpoint is called the diameter. the diameter is twice the size of the radius. a line segment that has its endpoints on the circular border but does not pass through the midpoint is called a chord. a circle is the same as 360 small circle up the number 0 . i hope this .
