Answer:
The correct option is b.
Step-by-step explanation:
The area of a rectangle is
\(A=length\times width\)
The area of rectangle is 48 square units and the width of the rectangle is 6 units.
\(48=length\times 6\)
Divide both sides by 6.
\(8=length\)
The length of the rectangle is 8.
In a right angled triangle,
\(\tan\theta=\frac{perpendicular}{base}\)
In triangle JKL,
\(\tan (\angle KLJ)=\frac{JK}{KL}\)
Opposite sides of a rectangle are same.
\(\angle KLJ=\tan^{-1}(\frac{6}{8})\)
\(\angle KLJ\approx 36.87\)
The measure of angle KLJ is 36.87. Therefore the correct option is b.
