another process is if you find sinQ and cosQ which will be respectively 4/5 and 3/5 by using trigonometric identity but that is not recommended

please in detail
i divided the numerator and denominator by cosQ in the recommended process
and for that another one use sin^2Q + cos^Q =1
and the other identities....i don't recommend it
ok
please send pic in this question
??
more useful you use Pythagoras theorem the numbers are Pythagorean numbers i missed it sry see 3,4,5 .....3^2+4^2=5^2
