Question

If sin theta=3/5, then find the value of cos theta​

Answer 1

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

Answer 2

Answer:

sin thita=p/h=3/5

b=√(5)upon2-(3)upon2-

b=√ 25-9

b=√16

b=4

and final=cos theta=b/h=4/5

cos theta=4/5. ans
