Question

if sin theta = 3/5, find
cos theta = _______

Please help me​

Answer 1

Answer:

3 is the opposite side and 5 is the hypotenuse therefore the adjacent side will be four as 3 4 and 5 form Pythagorean triplet

cos theta is equals to adjacent upon hypotenuse

therefore cos theta = 4 upon 5

Answer 2

Answer:

Take the help of a right triangle.

Step-by-step explanation:

sin theta = opposite/hypotenuse.

cos theta = adjacent/ hypotenuse.

adjacent = √(hypotenuse)^2 - (opposite)^2

= √25- 9 = 4

cos theta = 4/5
