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:
10626 ways
Step-by-step explanation:
Given
Number of students = 23
Prizes = 3
Required
Number of different outcomes for the top 3
This question will be solved using permutation formula because it implies selection of 3 students from 23
<em>Where n = 23 and r = 3</em>
The formula becomes
<em>Hence, there are 10626 ways</em>
