correct me if im wrong....but do you subtract the two numbers to get the answer or are you trying to figure out the circumfrence?

67.

This problem seems immensely tough, but it isn't.

The measure of angle KJL is equal to the measure of angle KML.

12x+8=10x+16

First, get the x on one side.

12-10=2

2x+8=16

Now, subtract 8

2x=8

Now, divide both sides by 2.

x=4

ok for problem #68, do 130-50 and you should get the angle for V

for 67 do the same thing but put the numbers in place of the letters

k=12 and L=8 subtract these and it should give you the value of j

k=10 and l=16 subtract these and it should give you the value of m

math is'nt my strongest subject but i beleive this is how you do it or you solve for the variables on both sides

For the first one....KJL aand KML are inscribed angles that intercept the same arc....inscribed angles that intercept the same arc are equal

So Rarinstraw's working is correct !!!!

Second one...in this situation....V will equal (1/2) the difference of arcs ZY and WX....so we have

V = (1/2) (ZY - WX)

V = (1/2) ( 130 - 50 )

V = (1/2) (80)

V = 40°
