Question

if cos theta = 3/5 then the value of sin theta is​

Answer 1

Answer:

sin theta=4/5

cos theta = 3/5

Answer 2

Answer:

cos theta = 3/5

and we know taht cos theta = Base / hypotenuse

and sin theta = perpendicular / hypotenuse

through pythagoras theorem we can find perpendicular

(H)^2 = (B)^2 + (P)^2

(5x)^2 = (3x)^2 + (P)^2

after solving we get P = 4x

sin theta = 4x/5x = 4/5

hope it helps
