Answer:
3%percent of $375 is $11.25 and 20% of $56.25 is $11.25 .
Step-by-step explanation:
Formula
First Part
As given
Total value = $375
Part value = $ 11.25
Put values in the formula
Percentage = 3 %
Second Part
Total value = $56.25
Part value = $11.25
Put the values in the formula
Percentage = 20%
Therefore 3%percent of $375 is $11.25 and 20% of $56.25 is $11.25 .
Answer:
Step-by-step explanation:
By using the cos square identity in trigonometry i.e., cos2ϴ = 1 – sin2 ϴ, we can evaluate the exact value of cos(33 ). For calculating the exact value of cos(∏/6), we have to substitute the value of sin(30°) in the same formula.
cos(30°) = √1 – sin230°
The value of sin30° is 1/2 (Trigonometric Ratios)
cos(30°) = √1 – (1/2)2
cos(30°) = √1 – (1/4)
cos(30°) = √(1 * 4 – 1)/4
cos(30°) = √(4 – 1)/4
cos(30°) = √3/4
Therefore, cos(30°) = √3/2
