Answer:
Step-by-step explanation:
x² - 17x + 72 = 0
Sum = -17
Product = 72
Factor = 8 , 9
x² - 17x + 72 = 0
x² - 8x -9x + (-8)*(-9) = 0
x(x - 8) -9(x -8) = 0
(x - 8 ) (x - 9) = 0
Length = (x - 8) units
Width = (x - 9) units
Sin = opposite/hypotenuse
cos = adjacent/hypotenuse
They are the same when opposite equals adjecent.
This only occurs when the angles are equal.
Answer: 45°
Answer:
r = 4
Step-by-step explanation:
side of square is the same as the diameter of the circle
if diameter is 8 then radius is 4
To find the volume you will multiply the length by the width by the height (V=lwh).
V = 9 x 3 1/4 x 2/3
V = 19 1/2 cubic inches.
To find the volume of any prism, you find the area of the base (length times width in this case) and then multiply it by the height.
