Answer:
cos y = r/q
Step-by-step explanation:
If we know sin y = 7/q, then we know that the base is 7 and the hypotenuse is q due to sine = opposite/hypotenuse.
If we know tan y = 7/r, then we know that the base is 7 and the right side is r due to tan = opposite/adjacent.
Cos = adjacent / hypotenuse
So cos y = r/q, because the right side is r and the hypotenuse is q.
The question is asking how many gram should are there from 55 grams to 70 grams.
This is a simple math problem, all that you must is:
55 - 70 = 15
Thus, from 5 grams to 70 grams is 70 grams.
Hope this helps! :)
