Answer:
X=
Y=
Step-by-step explanation:
The first one is 45-45-90 right angled isosceles triangle.
The length of the hypotenuse ie.X can be found with the help of Pythagoras Theorem.
where a and b are the remaining sides of the triangle,
X=
In the second triangle we have to apply trigonometry,
cos θ=
cos 30°=
=
Thus, Y= inches

Hello!
I will make approximations below to the nearest whole number
A. 2√32≈11
B. 5+√18≈9
C. √24≈5
D. √52-3≈4
E. 3√14≈11
F. √20+√26≈10
Based off of what we see here our even numbers are 
and 
.
I hope this helps!
We can write an equation in terms of n, the amount of nickels:
25(3n+3)+10(n+1)+5n=265.
Thus:
90n+85=265
Subtracting 85, we have:
90n=180
Therefore, n=2. As such, Danielle has 2 nickels, 3 dimes, and 9 quarters.
