Question

The terminal tower in cleveland ohio is 239 ft shorter than key tower also in cleveland the total heights of the two buildings is 1655ft find the heights of the buildings

Answer 1

T + k = 1655
k = t + 239

now we sub
t + t + 239 = 1655
2t + 239 = 1655
2t = 1655 - 239
2t = 1416
t = 1416/2
t = 708 ft <== terminal tower

k = t + 239
k = 708 + 239
k = 947 ft <=== key tower
