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

5x+2y=29
x+4y=13
Let's eliminate y;
To do so, multiply equation1 by 2;
10x+4y=58
x+4y=13
Subtract equation II from equation I to get;
9x=45
x=5
To solve for y, replace value of x in equation II,
x+4y=13
5+4y=13
4y=8
y=2
Answer:
yes they are.
Step-by-step explanation:
if you were to divide the numbers in the first triangle by 2.5 you would get the numbers of the other triangles and vice versa for the other triangle
Surface area: S=2LH+2LW+2WH=2x4x2+2x4x2+2x2x2=40 (cm)
Volume: V=LWH=4x2x2=16 (cm^3)
Ratio: 40:16 = 5:2
=> Answer is 5:2
