Answer:
8. Triangular Prism 11. Acute angle
Step-by-step explanation:
8. 2 triangular figures are attached onto the ends of the rectangular piece of the prism which lets me know that its a Triangular Prism
11. This is an Acute angle because it is not pointing at a right angle (90 degrees) and it is not an obtuse angle because the ray on the left does not exceed a right angle in other words it doesn't shift farther to the left but more to the right.
