Using the law of cosine for Triangle KJL, we can write:
Using the values of k,j and l, we can write:
Rounding to nearest integer, the measure of angle J will be 48 degrees.
So option B gives the correct answer

<h3 /><h3>Pythagoras theorem </h3>
The theorem states that the square of the longest side is equal to the sum of square of other two sides.
From the given question
Hypotenuse (ladder length) = 15ft
Adjacent = 7feet
Required
Height of the wall H
According to the theorem
15² = 7² + H²
H² = 225 - 49
H² = 176
H = 13.27feet
Hence the height of the wall from the question is 13.27ft
