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
Shkiper50 [21]

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:

\begin{gathered} cos35^{\circ}=\frac{21}{x} \\ x\times x=0 \\ (x)cos35=21 \\ \frac{cos35}{cos35}=0 \\ \frac{21}{cos35}=25.6362664 \\ 25.6362664 \\ 3
