Building a is 180 feet shorter than building b. the total height of the two buildings is 1520 feet. find the height of each building. what

Here is the set up:

a = b - 180
a + b = 1520

We have a systems of linear equations in two variables.

b - 180 + b = 1520

2b = 1520 + 180

2b = 1700

b = 1700/2

b = 850

Plug b = 850 into either equation.

I will use a + b = 1520.

a + 850 = 1520

a = 1520 - 850

a = 670

Building a is 670 feet. Building b is 850 feet.

B= 850 ft
a= 670 ft

b + (b-80) =1,520
2b=1700
b=850 a=670 =(1,520-850)
850-670=180 ( difference between a and b)
