Answer:

csc x = D

sec x = D

Step-by-step explanation:

In the ∆XZY, angle X is the angle of elevation

• the Opposite Side will be line segment ZY which is equal to 15;
• the Adjacent Side will be line segment XZ which is equal to 8
• and the hypotenuse is the line segment XY which is equal to 17

csc(∅) = hypotenuse/opposite

csc(x) = 17/15

sec(∅) = hypotenuse/adjacent

sec(x) = 17/8
