building A is 180 feet shorter than building B. The total height of the two building is1480 feet. find the length of each building

Answer 1

Let x = height of building B
Let x - 180 = height of building A
since their total height is 1480,
x + x - 180 = 1480
Solving,
2x = 1480 + 180
2x = 1660
x = 830 ft (height of bldg B)
x-180 = 650 ft (height of bldg A)
