Answer 1

This triangle utilizes the cos function. You know that cos(x) = side adjacent/hypotenuse, so our identity would be \[\cos(45)=\frac{ 16 }{ x }\]To solve for x, multiply both sides by x and divide both sides by cos(45) to get \[x=\frac{ 16 }{ \cos(45) }\]Dividing this out you get 22.627. Do you get it? Remember SOHCAHTOA!!!!!
