Answer:
<CDG and <CDB are supplementary angles.
Width of the rectangle is 5 units
<u>Explanation:</u>
Let length (l) = l units
Given,
width (b) = l-3 units
Area of rectangle = 40 units
We know,
Area of rectangle = l X b

If l = 8 units then, b = 8-3 units
b = 5 units
Therefore, width of the rectangle is 5 units.
Unknown. C is the hypotenuse, but this problem is solvable.
236.5% is the correct answer
<span>time for airplane = 11 am to 1 pm = 2 hr
distance travelled by plane = 2a ------- (speed of plane is a mph)
time for auto = 3 am to 1 pm = 10 hr
distance travelled by plane = 10(a – 200)
2a = 10(a – 200)
8a = 2000
a = 250 mph ----- plane
and 250 – 200 = 50 mph ----- auto </span>
