It should be 3)120 I tried to show the work best as possible just in case
Answer:
-3b^4 (6b^3 -b-5)
Step-by-step explanation:
Each term is divisible by 3b^4 so we can factor this out
3b^5 + 15b^4-18b^7
3b^4( b+5 -6b^3)
Rewriting the inside term
3b^4 (-6b^3 +b+5)
We can factor out a negative
-3b^4 (6b^3 -b-5)
Applying the angles of intersecting secants theorem, the measures of the arcs are:
m(KL) = 20°; m(MJ) = 80°.
<h3>What is the Angles Intersecting Secants Theorem?</h3>
When two secants intersect and form an angle outside the circle, the measure of the angle formed is half the positive difference of the measures of the intercepted arcs.
Given the following:
m∠MEJ = 1/2(MJ - KL)
30 = 1/2(MJ - KL)
60 = MJ - KL
KL = MJ - 60
m∠MFJ = 1/2(MJ + KL)
50 = 1/2(MJ + MJ - 60)
100 = 2MJ - 60
2MJ = 100 + 60
2MJ = 160
MJ = 160/2
MJ = 80°
KL = MJ - 60 = 80 - 60
KL = 20°
Thus, applying the angles of intersecting secants theorem, the measures of the arcs are:
m(KL) = 20°; m(MJ) = 80°.
