For 0x90degrees solve the equation 5tan x equals 1?

Answer 1

5tanx=1 turns into

tanx=1/5 then you use a calculator

use the calculator function tan^(-1)

this function should be the 2nd function of tan

then in the parenthesis that come up type in 1/5

you should get .1974

therefore tanx=1/5 => x=.1974
