Question

help, this is what i have so far but how do i simplify this?

Answer 1

t-h-i-s

Answer 2

isolate mJK by moving everything not JK to the other side.

remember to use inverse operations.

Answer 3

this question would actually be easier if you started with radian measure actually, then convert your radian answer to degrees if required.

since \[l = r \theta \] (length of arc = radius x angle in radians)

Answer 4

21 is to 2*pi*r as x is to 360 where x is the degree measure of arc JK.

21/(2*pi*14.32) = x/360

Solve for x.
