H= U"2 (SIN TITA)"2/2g R= U"2SIN 2 TITA /2g
If R=3H
then U"2SIN 2 TITA /g = 3 (U"2 (SIN TITA)"2/2g)
u"2 cancel u"2 and g cancel g

so we are left with
sin 2 tita= 3 (sin tita)"2 /2
cross multiply
recall sin 2tita= 2sin tita cos tita hence
2sin tita cos tita= 3 sin tita x sin tita /2
sin tita cancel sin tita.
we are left with
2 cos tita = 3 sin tita/2

you know sin tita/ cos tita = tan tita.
divide both sides by cos tita

2cos tita/cos tita = [3 sin tita/ 2 ]/cos tita
2= 3tan tita/2
tan tita= 4/3
tita= tan"-1 (4/3)

tita= tan "-1 (1.333)


tita= 53.1°


THE ANGLE IS 53.1°
