Answer:
a is adjacent, b is opposite, c is the hypotenuse
Step-by-step explanation:
see the attached figure to better understand the problem
In the right triangle XYZ we have
The side a and side b are the legs and the side c is the hypotenuse (the greater side)
The side a is the adjacent side to angle Y and is the opposite side to angle X
The side b is the opposite side to angle Y and is the adjacent side to angle X
The side c is the hypotenuse
The sum of the angles X and Y is equal to 90 degrees because are complementary angles
therefore
a is adjacent, b is opposite, c is the hypotenuse
