I am assuming you want to solve for x:-
Now cosec^2 2x = 1 - cot^2 2x so the equation becomes
3 cosec^2(2x) + 2 cosec 2x = cosec^2 2x
2 cosec^2 2x + 2 cosec 2x = 0
2 cosec 2x ( cosec 2x + 1) = 0
so 2 cosec 2x = 0 or cosec 2x = -1
cosec 2x = 0 or cosec 2x = -1
cosec 2x = 0 is indeterminate so we ignore the first one
cosec 2x = -1 can be written as 1 / sin 2x = -1
so sin 2x = -1
giving 2x = 270 degrees
Therefore x = 135 degrees answer
Answer: This may be late but the answer is C
Step-by-step explanation: You have to look at all your values and count up how many students can fit into each column of your histogram.
The answer is D. Because it is easier to add 9 and 2 and also 8 and 1.
Step-by-step explanation:
expand the bracke
so -5(X+6) is -5x-30=15
so
-5x-30=15 ( add 30 so that no number in the equation) 15+30 is 45
-5x=45(divide by 5 as 45 is multiple of 5)
45/-5=-9 (positive / negative is negative)
X=-9
Answer:
The length of the backboard is 105 cm.
Step-by-step explanation:
You can find the length be dividing area/width. The area is 18,900 cm squared. The width is 1.8 meters or 180 cm. 18,900/180 = 105 cm. You can check by multiplying length by width, if you get the area, then the answer is correct.
