(4^9)^5 is equal to 4^45. You multiply 9 and 5 to get 45.
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

Answer:
x = 18
Step-by-step explanation:
Subtract 5 on both sides:
-2x + 5 =- -31
-5 -5
-2x = -36
Divide by -2 on both sides:
-2x = -36
/-2 /-2
x = 18
