use the SohCahToa method
Use SOHCAHTOA, then cross multiply and divide.
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.

If you have the length of two of the sides and one other angle you can use the law of sines.
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
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
You can use the component method for finding two or more vectors. Use the X and Y axis. Ex. If you have 5 vectors given-Draw a cartesian plane for every vectors-Get the equivalent value of X and Y for Every vectors(use the SOHCAHTOA rules).-Get the summation of X and Y then use Phythagorean Theorem. For finding the Angle, use the Tan theta. Save
