The ladder and the outside wall form a right triangle
The length of the ladder is 97.8 feet
<h3>How to determine the
length of the
ladder?</h3>
The given parameters are:
Distance (B) = 22 feet
Angle of elevation (θ) = 77 degrees
The length (L) of the ladder is calculated using the following cosine ratio
cos(θ) = B/L
So, we have:
cos(77) = 22/L
Make L the subject
L = 22/cos(77)
Evaluate the product
L = 97.8
Hence, the length of the ladder is 97.8 feet

What is M when R = 200? *
Step-by-step explanation:
Answer:
W = 500 + 25x
Step-by-step explanation:
Jeremy’s pay started at $500 per week. Every year his pay will increase by $25 per week.
Now, after x years his pay per week will increase by $(25x).
Therefore, if we model the weekly payment of Jeremy by an equation, then it will be given by
W = 500 + 25x
where W is his weekly payment after x years. (Answer)
80y² - 5x²
Factorise
5(16y²-x²)
hope this helps
divide out any similar things, in this case, it is 5
put it outside the parenthesis, and leave the leftover inside the parenthesis
hope this helps
