3x²-12x-60=0
simplify by dividing by 3: x²-4x-20=0
cannot be factored, use the quadratic formula: √(b²-4ac)=√[(-4)²-4*1*(-20)]=√96=4√6
x=2+2√2 or x=2-2√2
Answer:
Arc JK: 27°
Arc NJ: 153°
Arc JL: 117°
My guess on arc KNM is 207°
My other guess for MJL is 297
JKM 180°
Step-by-step explanation:
According to the information, it can be inferred that the correct inequality is Mallory > Eva (option D).
<h3>How to identify who is closer to the surface of the water?</h3>
To identify who is closer to the surface of the water we must read the distance that each of the characters is.
In this case, the person closest to the surface is Eva, who is 5 feet from the surface.
Now we must identify which inequality corresponds to reality. In this case the inequality that is correct is:
This inequality is correct because Mallory is further from the surface than Eva.

ΔJKL, sin(JLK)=JK/KL=3/6=0.5
<JKL=30deg.
cos(JLK)=JL/KL
JL=KL*cos(JLK)=6cos(30deg.)
<JLK + <JLM = <MLK
30 + <JLM = 61
<JLM=31deg
in ΔMJL
tan(JLM)=JM/JL
JM=JL*tan(JLM)
=6cos(30deg.)*tan(31deg)
=3.12
