The lengths of the sides of the base are 2 ft
This is because the volume is the base times the height
if you take the volume and divide it by the height than you get 4, which means the area of the base is 4
This means that when you multiply the side lengths together you should get 4 and since you know the base is a square (so both sides are the same length) the answer is 2
Y is a 97 degree angle
Angle z is 83 because the sum of all interior angles in a triangle is 180
180-55-42 = z
83 = z
Angles y and z are supplementary angles, so they add up to 180.
Since z = 83 and 180 - 83 = 97, angle y is 97 degrees
The answer is 15:25 but when simplified it is 3:5
Total amount saved in 1st case :
Total amount saved in 2nd case :
( Here are number of months )
Let, after x months the amount saved in both cases is same.
So,
Amount saved :
Hence, this is the required solution.
