Answer:
1402.5 Cubic Units
Step-by-step explanation:
Volume of a Triangular Prism: V = 
b - base
h - height
l - length
15 is the height, 17 is the length, and 11 is the width (assuming which is the base).

The volume of the prism should be 1402.5 cubic units.
Answer:
77°, 103°
Step-by-step explanation:
x=103°
- z=x=103°
- y=180°-x=180°-103°=77°
-----------
∠5= 42°
∠3= 180°-42°=138°
