Answer:
cosecθ
Step-by-step explanation:
Please see attached picture for full solution.
cosecθ= 1/sinθ
cotθ= 1/tanθ= cosθ/sinθ
Step-by-step explanation:
So when a question asks what is x% of the y number. It's asking you to convert the x into decimal form by dividing by 100 and then multiply it by y. This gives you the equation: which gives you x% of y. so 15% of 43 is
. 43% of 300 is
.
the 12% of what number is 43 is a bit more tricky. It's asking you to instead find a number in which 12% of it is equal to 43. So instead of plugging solving for the percentage (which is already given) you solve for y. This gives you the following equation: . Now all you do is calculate 12/100 which gives you
. now divide both sides by 0.12 to solve for y. This gives you
43 is what percent of 106? This question is also a bit tricky, but instead of solving for y, you're solving for x. So plug in the known values, which gives you the equation: . Divide both sides by 106 to get
and now multiply both sides by 100. this gives you
which is the answer 40.57%
What percent of 43 is 6. This is asking the same thing just in a different way. So percentage = unknown, entire number = 43, entire number * percentage = 6. With these values we get the equation: . Divide both sides by 43 to get
now multiply by 100 to get
which is the answer 13.95%
