To solve this problem you must apply the proccedure shown below:
1- The ladder forms an isosceles triangle, because it has two equal sides.
2- Let's call the angle
. To calculate it , you can divide the triangle into two equal right triangles and the angle
will be divided into two equal parts too. Therefore, you can calculate the half of the angle and then multiply it by two, as following:



The answer is: 
Answer:
16z-48
Step-by-step explanation:
8(2z-6)
8*2z-8*6
16z-48
(4x^5-15x^3-10x^2)-(2x^5-5x^3-2x^2)
So, the first thing we will do is add like terms. But before that, lets get rid of both parenthesis. We'll just get rid of the first pair, and for the second pair, we will multiple everything in the second parenthesis by -1
4x^5-15x^3-10x^2-2x^5+5x^3+2x^2
Now, we will add like terms.
2x^5-10x^3-8x^2
Now, there's a common factor that all of these terms share; it's 2x^2. 2x^5 can be divided by 2, as well as -10x^3 and -8x^2 (these are the coefficients, number found in front of the variable.) So, we'll distribute 2
2x^2(x^3-5x-4) (we take the 2x^2 out by dividing all terms by 2x^2)
So, our answer would be
2x^2
Answer:
4.9 (rounded)
Step-by-step explanation:
Square root or 24 is 4.89, so it rounds to 4.9
Y = 25x - 5 is the equation.
