Given:
The area model.
The area of the shape is 82 square units.
To find:
The correct equation for the given situation.
Solution:
We know that, area of a rectangle is

The figure is divided into 3 rectangles. Using this formula, the area of each rectangle is



Now, the total area is equation to 82 square units.



Since the required equation is
, therefore, the correct option is C.

Answer:
40°
Step-by-step explanation:
We can find the tangent of ∠J using the trigonometrical ratios which may be expressed in the form SOA CAH TOA Where,
SOA stands for
Sin Ф = opposite side/hypotenuses side
Cosine Ф = adjacent side/hypotenuses side
Tangent Ф = opposite side/adjacent side
The hypotenuse is the side facing the right angle while the opposite is the side facing the given angle.
Considering triangle ΔJKL, where ∠L=90°, JK = 7.3 feet, and KL = 4.7 feet
As such, with respect to angle J, JK is the hypotenuse, KL is the opposite side
Hence
Sin J = 4.7/7.3
Sin J = 0.643835616
J = 40.08°
