Answer:
u=2t-v
Step-by-step explanation:
t=(u+v)÷2 |×2
2t=u+v
-u=v-2t |:(-1)
u=-v+2t
u=2t-v
We know the bottom triangle is a 45, 45, 90 triangle, so the hypotenuse is √2 times the value of the legs:
(√2)(√2)
=√4
=2
Now, we can use this to solve for y. The top triangle is a 30, 60, 90 triangle. The side we found above is the side across from the 30 degree angle. The side opposite the 60 degree angle is √3 times the side across the 30 degree angle. Therefore, we can solve for y by multiplying 2 by √3
y=2√3
Answer:
Required,
Step-by-step explanation:
Given volume and depth respectively,
and 
To find length and width of the rectanglular swiming pool we know,
Volume=length
heightdepth.
Let depth=D=x-3, length=L, width=W, then
After divide we will get 
with remainder -144.
Thus,
Now to find root of,
Thus,
X² + 11x - 26 = 0
x² - 25 = 0
(x + 13)(x - 2) = 0
(x + 5)(x - 5) = 0
x = -13
x = 2
x = -5
x = 5
