Answer:
a^3 +r^2
Step-by-step explanation:
a is multiplied three times so it goes to a^3
r is multiplied twice so it goes to r^2
No as it doesn’t go vertically through 1/3 on x axis
Answer:
is the answer
Step-by-step explanation:
First we need to substitute X and Y with their respective numbers
Then, following PEMDAS, We just need to simplify
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
