Sin= Opposite/Hypotenuse
Cos= Adjacent/Hypotenuse
Tan= Opposite/Adjacent
use the SohCahToa method
sohcahtoa SOH|CAH|TOA S= O opposite over hypotenuse _ H C=A adjacent over hypotenuse _ H T=O opposite over adjacent _ A
The longest length would be the hypotenuse. You can use SOHCAHTOA to find the length.

Just remember SOHCAHTOA, SOH is using the sine, only use this when you have the Hypotenuse and the Opposite. Sin(a)= O/H CAH is using the cosine, only use this when you have the Hypotenuse and Adjasent. Cos(a)=A/H TOA is using the tangent, only use this when you have the Opposite and Adjasent. Tan(a)=O/A
use the SohCahToa method
Use SOHCAHTOA, then cross multiply and divide.

Tyrone is socahtoa joe, i saw him vent in kfc

If you have the length of two of the sides and one other angle you can use the law of sines.

Sohcahtoa is an abbreviation (SOH) sine opposite hypotenuse (CAH) cosine adjacent hypotenuse (TOA) tangent opposite adjacent.
It means for any right angle triangle:- sine = opposte/hypotenuse cosine = adjacent/hypotenuse tangent = opposite/adjacent
It is a trigonometric equation for a right triangle, to find a non-right-angle angle. Using SOHCAHTOA, it is the opposite side divided by the adjacent angle
