Question

the value of sinx = 7/25,x lies in 2nd quadrant,then the value of tan x is...​

Answer 1

Answer:

Hi

sinx = 7/25

x lies in 2nd quadrant then tanx is -ve

hypotenus square minus opposite side square is equal to adjacent side

adjacent side square 25^2 - 7^2 = 625 - 49 = 576

adjacent side square = 576

adjacent side = 24

tanx = opposite side/adjacent side

tanx = -24/7

Therefore tanx = -24/7

hope it helps
