Answer:
63.2
Step-by-step explanation:
So, we can break this shape into 2 shapes. A trapezoid and a rectangle.
For the trapezoid, we can do the formula.
((2.8 + 7.2)4)/2 = 20
Next, we can do the rectangle.
6 x 7.2 = 43.2
Now we can add them up and get our final answer.
43.2 + 20 = 63.2
Recall the half-angle identity:
So in order to find
, we only need to know the value of
. But there are two possible values. To decide which to take, we use the given information: we know that
lies in quadrant III, which means
, so
, which places
in quadrant II. In this quadrant, the sine of angle is positive, and so
is an angle of a ray whose terminal point,
lies on the circle
. The
-coordinate is all we need to know in order to find that
. So,
Answer:
7963.9

Answer:
Three times a number plus 16
To solve this, we simply need to break down the words and turn each part into an equation.
"Three times"
This shows that we will be multiplying 3 and something.
3*
"a number"
This shows that the number we will be multiplying 3 by is "n," which represents a number.
3*n or 3n
"plus 16"
This shows we will be adding 16 to the rest of the equation.
3n+16
Using the logic above, we can see that the equation to represent this is 3n+16.
