Answer:

Step-by-step explanation:
For this triangle we have to

We want to find the length of b
We know that the sum of the internal angles of a triangle is 180 °
So

Now we use the sine theorem to find the length of b:

Then:

3 1/2 is equal to 7/2. 1 1/2 is equal to 3/2. 7/2 times 3/2 is equal to 21/2, which is equal to 10 1/2.
Answer:
Step-by-step explanation:
volume=9×3×4+6×3×4+3×3×4=(9+6+3)×3×4=18×12=216 yd³
Answer:
Formula for finding the volume of a trapezoidal prism =\frac{1}{2}(b_1+b_2)h
Step-by-step explanation:
A and B are correct because 96/100 is equivalent to 0.96, which is also 96%.
