What is the permutation and combination?
Permutation and Combination form the principles of counting and they are applied in various situations.
A permutation is a count of the different arrangements which can be made from the given set of things. In permutation the details matter, as the order or sequence is important.

Answers
Answer:
Below in bold.
Step-by-step explanation:
C1 = 180 - C2
= 180 - (170-2x)
= 10 + 2x
So B3 = 10+2x (alternate angles).
and B2 = 90 - B3
= 90 - (10 + 2x)
= 80 - 2x.

To determine the length and width of a rectangle, we can set up an equation using the given information and solve for the variables. By substituting the width back into the equation for the length, we find that the width is 9 meters and the length is 13 meters.
Explanation:
To solve this problem, we can start by using the given information to create equations. Let's assume that the width of the rectangle is 'w' meters. According to the problem, the length of the rectangle is 5 meters or less than twice the width, so the length can be represented as 2w - 5 meters.
The formula to calculate the perimeter of a rectangle is 2l + 2w, where 'l' is the length and 'w' is the width. We are given that the perimeter is 44 meters, so we can set up the equation as follows:
2(2w - 5) + 2w = 44
Simplifying the equation, we get:
4w - 10 + 2w = 44
Combining like terms, we have:
6w - 10 = 44
Next, we can isolate the variable by adding 10 to both sides:
6w = 54
Finally dividing both sides by 6, we find that:
w = 9
Therefore, the width of the rectangle is 9 meters. Substituting this value back into the equation for the length, we find:
l = 2w - 5 = 2(9) - 5 = 18 - 5 = 13 meters.

tan -30 is the same as tan 330, which is -
cot -π = 1 / tan π, which is 1 / 0, and you can't divide by 0, so cot -π is undefined
