WebAnswer (1 of 19): sin theta=4/5 =P/h so p=4 ,h=5 then b=sqrt(h^2-P^2) b=sqrt(5^2–4^2) =sqrt(25–16)= sqrt(9) =3 cos theta =b/h = 3/5 sin theta=4/5 =P/h so p=4 ,h=5 then b=sqrt(h^2-P^2) b=sqrt(5^2–4^2) =sqrt(25–16)= sqrt(9) =3 cos theta =b/h = 3/5 Something went wrong. Wait a moment and try again. Try again Web3 feb. 2015 · If sin of theata=4/5, then I know the hypotenuse is 5. I then assumed that this would be a 3,4,5 triagle. Cot=cos (theta)/sin (theta). I got 0.75. (3/4). I don't know if 3/4 is correct. Also, it's in quadrant 2...would that mean -3/4? I am all over the grid lost here. I tried to solve this problem but I really don't know how or what steps to take.

WebSince sin (theta)=4/5, you can say the side opposite theta is 4 and the hypotenuse is 5. Now you are just missing one side. You can use the Pythagorean Theorem to solve for that side, or you could recognize that this is a 3-4-5 triangle. Either way, the adjacent side (along the x-axis) is 3. Now you know each side's measure. WebWe noted above that the values of sine repeat as we move through an angle of 360°, that is, sin (360° + θ) = sin θ . We say that the function y = sin θ is periodic with period 360°. Thus, the graph may be drawn for angles greater than 360° and less than 0°, to produce the full (or extended) graph of y = sin θ. how to make a collage on fb

All steps. Final answer. Step 1/2. Given that: sin θ = − 4 5. Here θ lies in 3rd quadrant i.e. π θ π π < θ < 3 π 2. Use the definition of sine to find the known sides of the unit circle right triangle. The quadrant determines the sign on each of the values. sin ( θ) = o p p o s i t e h y p o t e ν s e. jo weldon historian
