Answer:
20.25
Step-by-step explanation:
Percentage solution with steps:
Step 1: Our output value is 135.
Step 2: We represent the unknown value with $x$
.
Step 3: From step 1 above,$135=100\%$
.
Step 4: Similarly, $x=15.\%$
.
Step 5: This results in a pair of simple equations:
$135=100\%(1)$.
$x=15.\%(2)$
.
Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both
equations have the same unit (%); we have
$\frac{135}{x}=\frac{100\%}{15.\%}$
Step 7: Again, the reciprocal of both sides gives
$\frac{x}{135}=\frac{15.}{100}$
$\Rightarrow x=20.25$Therefore, $15.\%$ of $135$ is

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
