Answer:
72
Step-by-step explanation:
Enter the expression into your calculator.
__
If you're doing this by hand, follow the Order of Operations. The expression is the difference of a quotient and a product. The quotient is on the left, so it is figured first.
252÷3 = 84
The product is figured next.
3(4)(1) = 12(1) = 12
Then the difference is figured:
84 -12 = 72
The simplified result is 72.
Draw a picture of the problem.
let ∅ be the angle formed in the first quadrant such that its y coordinate is twice its x coordinate.
The lengths are denoted 2a and a.
Joining the point (0, 0) to the point described, in the first quadrant, we have a right triangle with side lengths
, where 
is the hypotenuse, found by the Pythagorean theorem.
sin∅=opposite side/hypotenuse=
Now consider the reflection of the red line segment with respect to the x-axis, the ratio of the distances described still holds. Since here we are in the fourth quadrant, the sine is negative, so sin is
