Question

if cos theta=√3/5 then find sin theta and tan theta ?
​

Answer 1

Answer:

Step-by-step explanation:

cos theta=/3/5=base/hypotenuse

by Pythagoras theorem

(hypotenuse)^2=(base)^2+(perpendicular)^2

(5)^2-(/3)^2=(perpendicular)^2

/22=perpendicular

sin theta=perpendicular/hypotenuse=/22/5

tan theta=perpendicular/base=/22//3
