Answer: 12 for accurate 12.4
Step-by-step explanation: This is easy all you needed to do was divide 9,674.48 by 780.20 and get 12.4
The area of a parallelogram is base times height.
We can find the height by deriving a right triangle from the 60 degree angle and the 6 cm hypotenuse
sin(60°) = opp/hyp = x/6
√3/2 = x/6 Multiply both sides by 6
3√3 = x
x = 3√3
The height is 3 √3
Area = base x height
Area = 3√3 * 8
Area = 24 √3 cm²
Answer is C) 24 √3 cm²
Answer:
252 in²
Step-by-step explanation:
Recall area of regular polygon is A= (1/2)*(perimeter)*(apothem)
Area = (1/2)*(63)*(7)
= 252 in²
The proportionality constant is 1/3 meaning y is 1/3 of x or x is 3×y
Add 9.5 to 42.1 and then you want to divide that answer by 6 to get x=8.6
