180 - 70 = 110
110 - 35 = 75
The third angle is 75
        
             
        
        
        
Answer:
6536 cubic in
Step-by-step explanation:
1. Split both the prisms apart- In doing so, you can simplify the problem.
2. Put in the #'s for the formula which in this case is V=L*W*H, we will start with the formula for the front one, V=7*8*1 or V=7*8
3. answer for the front is 56 cubic in, now we solve for the other half.
4. V=9*1*90 or V=9*90 which is 6480 cubic in.
5. add 6480 and 56 and your answer is 6536 cubic in as your answer.
Hope this helped ;D
 
        
             
        
        
        
First you are going to solve for f. 
6f = -2 
you must get f alone so you divide both sides of the equation by 6 which becomes ....
f = -3
now you add the absolute value sign to -3. absolute value is how far away your answer is from 0. -3 is 3 away from zero so f = 3
        
             
        
        
        
Answer:
A parallelogram because the figure described has exactly two pairs of parallel  sides.
Step-by-step explanation:
A trapezoid only has one pair of parallel sides so it can't be that and it can't be a parallelogram with exactly one pair of parallel sides because they have two pairs.
