tan = √3
STEPS:
based on 1,2,√3 triangle (30°,60°,90°)
where :
1 is opposite 30°
√3 (around 1.7) is opposite of 60
2 is opposite of 90°
smallest side is opposite of smallest angle
largest side is opposite of largest angle
cosθ = 1/2 = adjacent/hypotenuse so
adjacent = 1
hypotenuse = 2 so
opposite must be √3
tan = opposite/adjacent = √3/1 = √3
