using Pythagorean Theorem
x^2 +b^2 = c^2
x^2 +12^2 = 13^2
x^2 +144 = 169
x^2 = 25
x = sqrt(25) = 5
x = 5
number one because if you do the math it's the o nly one that's different
Answer:
Elizabeth washes 99 windows each day.
Step-by-step explanation:
Given:
Total number of windows (N) = 2480
Marie washes windows = 4 times Elizabeth washes.
Elizabeth washes same number of windows for 5 days.
Let the number of windows washed by Elizabeth each day = 'x'.
Therefore, over the 5 days, the windows washed by Elizabeth = 
Now, as per question:
Marie washes windows = 4 times Elizabeth washes.
So, number of windows washed by Marie = 
Now, total number of windows = Windows washed by Marie + Windows washed by Elizabeth
So,

Therefore, Elizabeth washes 99 windows each day.
Answer:

Step-by-step explanation:
We are given that a function

We have to find the derivative of the function
Let 

Taking ln on both sides

By using 
Differentiate w.r.t x




Differentiate y w.r.t x

Using the value of du/dx

180-94-41 = 45
180-45-111 = 24
The answer is x is 24 degrees
