Answer:
there are three basic trigonometric ratio:sine,cosine and tanget.given a right triangle,you can find the sine (or cosine,or tanget)of either of the non-90°angles
Step-by-step explanation:
sine=length of the leg opposite to the angle. length of hypotenuse
cosine=length of the leg adjacent to the angle.length of hypotenuse
tanget=length of the leg opposite to the angle.length of the leg adjacent to the angle
