Question

if tan theta equal to 1 then . find cos theta​

Answer 1

Answer:

cos theta = sin theta

Step-by-step explanation:

Given; tan theta=1

SOLUTION;

tan theta=sin theta / cos theta

1 = sin theta / cos theta

cos theta = sin theta

Answer 2

Step-by-step explanation:

tan theta=1

opp/adj=1....

in a triangle

hyp=(opp^2 +adj^2)^1/2

opp=1

adj=1

therefore # hyp= root of 2...

cos=adj/hyp=1/root 2

*cos=1/root 2*
