Question

sin A=4/5 find tan A

Answer 1

first use Pythagoras theorem to find base ...
ur base will be 3 ..now find tan
u have p=4 ,b=3,h= 5
tan A=p /b =4/3 ..
hope it help

Answer 2

sinA =4/5 = P/H
H=5, P=4, B =?
H sq. = P sq. + B sq.
5 sq. = 4 sq. + B sq.
25 = 16 + B sq.
25-16 = B sq.
9= B sq.
3= B
TanA = P/B
TanA= 4/3
