Answer:
The measure of angle KJL is 40°.
Explanation:
Givens


Notice that
, by definition sum of arcs.
Replacing given values, we have

Which means

Notice that arc KP is the subtended arc by angle KJL.
We know that the angle formed by a tangen and a secant is equal to one-half of the difference of the intercepted arcs.

Therefore, the measure of angle KJL is 40°.
