Answer:

39.53 ft^2

Step-by-step explanation:

We can find the area of the rectangle

A = l*w

= 12*3 = 36

And the area of the semicircle

A = 1/2 pir^2

The diameter is 3, the radius is 3/2

=1/2 pi* (3/2)^2

= 1/2 *3.14 * 9/4

3.5325

Add the two areas together

36+3.532539.5325

Rounding to the nearest hundredth

39.53 ft^2

Please help !! thank you so much!!

Step-by-step explanation:

we know that:

$tan(x - y) = \frac{tanx - tany}{1 + tanx \times tany}$

using this, we can see that x = 73 and y = 13

using this, tan(x-y) = tan(73-13) = tan(60)

therefore, A = 60

we know that tan(60) = √3

therefore, B = 3
