Express x and y in terms of trigonometric ratios of 0.
Georgia [21]
SIN(θ) = OPPOSITE / HYPOTENUSE = X / Y 
COS(θ) = ADJACENT / HYPOTENUSE = 2 / Y 
TAN(θ) = OPPOSITE / ADJACENT = X / 2 
CSC(θ) = 1 / SIN(θ) = 1 / (X / Y) = Y / X 
SEC(θ) = 1 / COS (θ) = 1 / (2 / Y) = Y / 2 
COT (θ) = 1 / TAN(θ) = 1 / (X / 2) = 2 / X 
HUNEY, YOU HAVE ALL OF THE VALUES, NOW JUST SOLVE FOR X AND Y THEN... 
FOR EXAMPLE: 
SIN(θ) = X / Y X = Y * SIN(θ) 
COS(θ) = 2 / Y Y = 2 / COS(θ) 
TAN(θ) = X / 2 X = 2 * TAN(θ) 
SO ON, SO FORTH HUN U GET IT
