Question

Please I need help, if you can

Answer 1

Answer:

First building = 456

Second building = 438

Third building = 383

Step-by-step explanation:

First building = 73 + x

Second building = 55 + x

Third building = x

Total height of three buildings = 1277

(73 + x) + (55 + x) + (x) = 1277

73 + x + 55 + x + x = 1277

128 + x + x + x = 1277

128 + 3x = 1277

3x = 1149

x = 383

This is the height of the third building.

First building = 73 + x = 73 + 383 = 456

Second building = 55 + x = 55 + 383 = 438
