Answer:
Volume = 150 m^2
Step-by-step explanation:
Using Volume formula of prism, we get L*W*H, but since we know the area of the base is L*W, which is 12.5, we multiply 12.5 by 12 to get 150 m^2.
D. The measure of TRU is 72
Answer:
HI, IG, GH
Step-by-step explanation:
First, you need to find the missing angle; do this by subtracting 48 and 89 from 180. This means the missing angle is 43. The smallest side will be across from the smallest angle. So in order of least to greatest, the sides are HI, IG, GH.
The sum of two numbers will be zero when you have the same number and one is positive and one is negative. For example 1 + -1= 0
