tanx=(opposite)/(adjacent)=5tanx=oppositeadjacent=5

Explanation:

color(red)(Cotx=0.2cotx=0.2 , color(red)(tanx?tanx?

In a right triangle there is a slope side-hypotenuse,
opposite side and adjacent side.

:.cotx=0.2=1/5

:.cotx=(adjacent)/(opposite) ,adjacent=1 opposite=5

:.tanx=(opposite)/(adjacent)

:.tanx=5/1

:.color(red)(tanx=5

on calculator:

:.arctan(tan^-1)0.2=11.30993247°=11°18'35.7''

:.tan11.30993247=0.199999713 =0.2 to the nearest 1 decimal

:.0.199999713 1/x =5.000007173= cotx
