Answer:
Step-by-step explanation:
As we can see the given diagram represents an isosceles trapezoid.
So we can say from the properties of isosceles trapezoid.
As the required side XY has a length y+1, So we can write
Number of boys=x
number of girls=y.
We can suggest this system of equations:
x/y=8/7 ⇒x=8y/7
x+y=195
this system of equations can be solve by substitution method.
(8y/7)+y=195
least common multiple=7
8y+7y=1365
15y=1365
y=1365/15
y=91
x=8y/7
x=8*91 / 7
x=728/7
x=104
Answer: there were 104 boy campers and 91 girl campers.
It's the same thing, the different is depends in which side was x
<span> √3 - i = 2e^(5πi/6)
(2e^(5πi/6))^-10 = 2^-10 * e^(-25πi/3)
= 2^-10 * (cos(-25π/3) + isin(-25π/3))
= 2^-10* (1/2 - i(√3/2)) </span>
