The angle would be 70 degrees because 180-110=70
Perimeter is the sum of all the sides of the shape
do you know the length of each side of the parallelogram?
V = l * w * h
240 = 20* h
divide both sides by 20
12 = h
height = 12 inches
In such type of questions, all that you are supposed to do is, use basic mathematics to eliminate any one of the given two variables.
Check out the equations if in case you can multiply any of the given ones with a -1 and add the two equations,eliminating one of the variables.
