I'd say the answer would be 8.
Answer:
Answer:
2.215=2 43/200
Step-by-step explanation:
Showing the work
Rewrite the decimal number as a fraction with 1 in the denominator
2.215=2.215/1
Multiply to remove 3 decimal places. Here, you multiply top and bottom by 103 = 1000
2.215/1×1000/1000=2215/1000
Find the Greatest Common Factor (GCF) of 2215 and 1000, if it exists, and reduce the fraction by dividing both numerator and denominator by GCF = 5,
2215÷5/1000÷5=443/200
Simplify the improper fraction,
=2 43/200
In conclusion,
2.215=2 43/200
<span>The question is tricky. But any way the longest side of a right triangle is always the hypotenuse. So we know the hypotenuse if 15 cm.
Now, consider the Pythagorean theorem:
a^2 + b^2 = h^2, where a and b are the sides of a right triangle and h is the hypotenuse.
We know one side is 12cm and the hypotenuse is 15 cm, so:
12^2 + b^2 = 15^2, or </span><span>1</span><span>44 + b^2 = 225
subtract 144 from either side to get
b^2 = 225 - 144 = 81
now take the square root of either side to get
b = 9
The third side is 9 cm</span>
We know that
The arrangement forms an isosceles triangle with equal legs of 8 miles.
The angle between the legs is equal to

°
Therefore, the other two angles are
Angles = (180-60)/2 = 120/2 = 60°
It can, therefore, be noted that all angles are equal and thus the resulting triangle is actually an equilateral triangle and thus all the sides are equal.
Hence
the answer is
the distance between the two ships is 8 miles apart
alternative Method
Applying the law of cosines
<span>c²=a²+b²-2*a*b*cos C
</span>where
a=8 miles
b=8 miles
C is the angle between the legs-------> 123-63------> 60 degrees
c is the distance between the two ships
so
c²=8²+8²-2*8*8*cos 60------> c²=64-------> c=√64------> c=8 miles
