Identify the trig ratio that may be used to find the marked unknown side.

In a right triangle, while 10 degree angle's ​ (a)   ratio is 0.985 , 80 degree angle's ​ (b)   ratio is ​ 0.985. Because they are ​ (c)   angles. The one angle's adjacent leg is another one's ​ (d)  

• Adjacent Leg/ Hypotenuse

• Opposite Leg/Hypotenuse

• complementary

• opposite leg
