Answer:
174 ft²
Step-by-step explanation:
Assuming you're interested in the area of the figure, you can compute it as the sum of the areas of the triangle and rectangle.
The unknown side of the triangle can be figured from the overall dimension of the rectangle and the two lengths that are not part of the triangle base:
6 ft + triangle base + 6 ft = 18 ft
triangle base = 18 ft - 12 ft = 6 ft
Then the area of the triangle is ...
A = 1/2bh = 1/2(6 ft)(4 ft) = 12 ft²
__
Of course, the area of the rectangle is the product of its length and width:
A = LW = (18 ft)(9 ft) = 162 ft²
__
The total area of the figure is the sum of these:
area = triangle area + rectangle area
area = 12 ft² +162 ft²
area = 174 ft²
Answer:
denominator
Step-by-step explanation:
The denominator tells how many equal parts the whole is subdivided into. The numerator tells the number of those parts that are under consideration.
The value of the expression 
is 4 and the exact value of 
is 
<h3>How to determine the trigonometry expression?</h3>
The point on the unit circle is given as:
A point on a unit circle is represented as: (x,y), such that:
cos(t) = x and sin(t) = y.
This means that:
Calculate tan(t) using:
So, we have:
Evaluate
The expression is then calculated as:
Evaluate each term
Evaluate the sum
Hence, the value of the expression is 4
