The arrangement forms an isosceles triangle with equal legs of 8 mi. The angle between the legs is,
123-63 = 60°. Therefore, the other two angles ares:
Angles = (180-60)/2 = 120/2 = 60°
It can therefore be noted that all angles are equal and thus the resulting triangle is actual an equilateral triangle and thus all the sides are equal.
It can be concluded that the ships are 8 miles apart.
Answer:

Step-by-step explanation:
Given the equation:

To find:
The solutions of given equation in the range [0, 2
) i.e. 0 can be in the answer but
can not be there in the answer.
Solution:
Taking
common, we get:

The solutions can be given as:
OR 
Let us solve both the equations one by one:
First equation:

Second equation:

Therefore, the answers as a comma separated list are:

Let F be the father's current age, and E be Evie's current age.
F = E + 36 this is the current relation between the ages
F + 3 = 5(E + 3) this the relationship in 3 year (hence the + 3)
Then solve by substituting one equation into another:
(E + 36) + 3 = 5(E + 3)
E + 39 = 5E + 15
24 = 4E
6 = E
Evie's current age is 6.
If you double the width you make a similar prism with a scale factor of two, the surface area of the similar prism will increase as the square of the scale factor
