At midnight, the tempertuare was 31.2 degrees below 0, and in the morning, it was 6.7 degrees below 0
<span>3x + 2x = 90 {the two angles add up to 90°}
5x = 90 {combined like terms}
x = 18 {divided both sides by 5}
angle 1 = 3x
= 3(18) {substituted 18, in for x, into 3x}
</span><span>= 54° </span><span>angles add up to 90°
angle 1 = 3x
angle 2 = 2x

Use a calculator it will help.
The cube made up of 8 cubes would have a greater amount of volume. We can infer this without doing any math because a row is neither tall or deep to allow for great volume while a cube made up of other cubes is deep allowing for a bigger volume than the row.
