Answer
1. 9
1. 13
1. 147
1. 7/3
1. 9
Step-by-step explanation:
Algebraic equations
1. 2x=18
2. x-5=8
3. (x/7)=21
4. 3x+5=12
5. 2x=18
I got:
−
8
f − 16
g

We know that
Applying the law of cosines
<span>c²=a²+b²-2*a*b*cos C
</span>in this problem
a=176.27 miles
b=222.34 miles
C=38.59°
c=<span>the distance between the planes
so
</span>c²=176.27²+222.34²-2*176.27*222.34*cos 38.59°----> c²=19239.15
<span>c=138.71 miles
the answer is
138.71 miles
