Answer: 56 units
Solution: (in the pic below)
Answer:
48cm^2
Step-by-step explanation:
We can break the composite figure into two pieces.
We take the bottom rectangle and determine its area
The figure is 10 cm by 2 cm
A = 10*2 = 20cm^2
The height of the vertical rectangle is 9 cm -2 cm = 7 cm
The width is 10 cm - 6 cm = 4 cm
The figure is 7 cm cm by 4 cm
A = 7*4 = 28cm^2
The total area is the sum of the two areas
20 cm^2 + 28 cm^2 = 48 cm^2
In order to find the missing variable you need to use the sine of the given angle. I attached an image with the work, hope it helps!
Answer:
x=2, -4
Step-by-step explanation:
The equation is 
. The x-intercept is the point(s) where the function intersects the x axis, so this value can be found by plugging in 0 for y. doing so results in 
. Then, solve for x by moving 18 over, dividing by -2, square rooting both sides, and subtracting 1 to find the value of x.
