Answer: The expression which must fill in each blank space to complete step 3 is; Choice B; Cos(A)Cos(B).
Which expression must fill in each blank space?
From the task content; It follows that the mathematical evaluation is in a bid to derive the Trigonometric identity for Tan (A-B).
From observation, it follows that the required expression is; cos(A)sin(B). This is because upon division of each term by the expression, the result is as in Step 4.
Answer:
So, a repeated rational can be :->
--> 0.33333333...
Which can be expressed as 1/3 hope this helps
Answer: 840 square inches
1. Split the figure into two rectangles.
2. Find x (there are other missing sides, but you do not need to know them).
x = 40 - 10
x = 30
3. Find the area of the two rectangles. Remember: A = lw.
Top rectangle: (10)(30) = 300
Bottom rectangle: (18)(30) = 540
4. Add the rectangles' areas together.
300 + 540 = 840
Do you have a chart or some other information?
