Question

given that tan theta=5/12 and angle theta is an acute angle find sin theta and cos theta

Answer 1

viewed as a right angled triangle

tan(x)=512

can be thought of as the ratio of opposite to adjacent sides in a triangle with sides 5,12 and 13 (where 13 is derived from the Pythagorean Theorem)

So

sin(x)=513

and

cos(x)=1213Answer:

Step-by-step explanation:

Answer 2

Sin theta = 5/13

Cos theta = 12/13...

Is this correct..? Hope it helps
