Answer:
A
Step-by-step explanation:
Note the expansion
tan(a - b) = 
We are given the right side of the expansion , then left side is
tan(
-
)
= tan(
)
= tan (
) → A
First, convert the percent into a decimal. You can make any percent into a decimal by moving the % sign two places to the left and making it into a decimal point.
70% = 0.70
In mathematics, if can also mean multiply.
0.70 * 50 = 35
So, 35 is the answer to this question.
Because the fence's dimensions is 30 feet by 10 feet, you can assume that one side of the pool is 30 feet while the other, non-congruent side, is 10 feet. The formula for perimeter, which you are trying to find, is 2L+2W=P. In this problem, 30 will be your L and 10 will be your W. Therefore, 2(30) +2(10)=80.
So 80 feet will be your answer.
Your answer is 3/2 i know for a fact
