Answer:
<h2>The measure of angle KJL is 40°.</h2>
Step-by-step 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°.
Answer:
an apparent solution that must be rejected because it does not satisfy the original equation.
Step-by-step explanation:
So 12 = 2 + 20t -5t^2
5t^2 -20t + 10=0
t^2 -4t + 2 = 0
