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:
