Hello I need help with question 12! I will give you a great rating! Please help, I’m not sure how to do this. Also this is not a
quiz this is practice
1 answer:
Given the following question:
Lable all the sides of the triangle:
Hypotenuse is the missing side
Right angle is the opposite
Adjacent is equal to 21
We have all of our sides so now we won't get them mixed up when finding the missing value of this triangle.
sin =
opp/hyp
cos =
adj/hyp
tan =
opp/adj
Since we are given the adjacent side and we are trying to find the hypotenuse we will solve for cos since we have the adjacent side but we need the hypotenuse
cos(35)=21/x
Now solve:

The least number should always start off with negatives if there are any. In this case there is so we can start with -2 as our least amount. Next are the small fractions. If you're allowed a calculator, I would use that to find what the decimals will look like for each fraction:
After -2 the next least number is 0 and the next one is the fraction or decimal closest to the number 0 which is 0.4
The next number would be from the fractions we solved earlier. 0.5 and 0.625 would follow 0.4 and then 1.1 and 1.6667(solved for from fraction).
Here is the list:
