If a number is increased by its square, the result is 72 find the number
gregori [183]
Translating into a mathematical equation:

n + n^2 = 72

Rewriting,    n^2 + n - 72 = 0
Factoring,    (n+9)(n-8) = 0
Solving for n:  n = -9 or n = 8

You must check both answers before accepting one, the other or both.

Example:  suppose we check out n = 8.  Then  8 + 8^2 = 72 is true, and n = 8 is a solution.  Is n = -9 a solution?  Try it.

vfiekz [6]

Answer:

60

Step-by-step explanation:

to find w:

sin(44) = w/30

w = 30sin(44)

w = 20.8 to 1 decimal place

to find x;

cos(x) = 20.8/45

x = cos^{-1}(20.8/45)

x = 62.46940334

x = 60

What function to use and how to use it
Lena [83]

That's the wrong right triangle to draw.  Reading the problem carefully we want this one, figure attached.

So we have the usual 30/60/90 triangle but not to scale.  The sides come in ratio 1:√3:2=x:100:hypotenuse.  So

x = 100/√3 ≈ 57.735

We add that to our 133.2 for the total height of the Cyclone, 190.935.

Answer: 190.9
