D)An acute angle <90 degrees
Step-by-step explanation:
Answer:
72 
Step-by-step explanation:
Volume for a triangular prism =
a · c · h
A = Height. C = Width. H = Length.
A = 3 yd. C = 8 yd. H = 6 yd.
V = 114 yd.
V = 114 yd ÷ 2 yd = 72
.
14.
4(5.6) = 4(6.0 - 0.4) = 4(6.0) - 4(0.4) = 22.4
16.
4(6 + 7) = 4(6) + 4(7) = 52
18.
14(10 - 5) = 14(10) - 14(5) = 70
subtract 75 from 120
120-75 =45 more campsites
