Question

Given sinx=4//5 and cosx=35 .

Answer 1

Given : Sin x = 4/5 and Cos x = 35 = 35/1

tan x = $\frac{Sin x }{Cos x}$

tan x = $\frac{4/5 }{35/1}$

tan x = $\frac{4}{5}\div \frac{35}{1}$

During the division of fractions flip the 2nd fraction after division sign and change the middle division sign to multiplication

tan x = $\frac{4}{5}\times \frac{1}{35}$

tan x = $\frac{4\times 1}{5\times 35}$

tan x = $\frac{4}{175}$
