Answer:

B.   A = 119.1 in.²

Step-by-step explanation:

A = area of trapezoid - area of circle

A = ½(b1 + b2)h - πr²

A = [½(27 + 12)(14) - 3.14159(7²)] in.²

A = 119.1 in.²

Which of the following equations could be used to solve for x in the triangle shown? tan48°=10/x

Acronym to remember the 3 basic trigonomic functions: 

Soh - Cah - Toa 

             opposite
sin = --------------------
            hypotenuse

              adjacent 
cos = -------------------
             hypotenuse

             opposite 
tan =  -----------------
             adjacent 


In your case, you can set up a sine trigonomic function, like this: 

Sin 48 = 10      (adjacent)
               -----  
                 x       (hypotenuse)

                       10
 (x) Sin 48 = ------ (x)
                         x

  (x) Sin 48 = 10 
 --------------   ------------- 
  Sin 48         Sin 48 

Plug in 10(sin)(48) into a calculator.

x = 7.43


I just realized that you didn't ask me to find the answer, but now you will know even more than you need to :D

Find an equation of the line described (3,7) (0,0)
Colt1911 [192]
The formula of the line is
y=mx + b
The likes goes through the point (0,0)
that means that y-int = 0, b=0
y=mx
So we need to find only slope.

m= \frac{y_{2}-y_{1}}{x_{2}-x_{1}} =  \frac{7-0}{3-0} = \frac{7}{3} 



So, y= \frac{7}{3} x
