Since you didn’t put the numbers to find the amount, I’ll teach you how to.. Once you have the decimal figure, multiply it by the number for which you seek to calculate the percentage
Tan(E) = 6/8 =3/4
tan(E) (opposite side)/(adjacent side)
1,800 is your answer because 1,200/72=16.6666667 and 1,800/108=16.6666667.
