Let's assume
height of building in Makkah as x
since, the building in Dubai is 745 feet taller than the building in Makkah
So, the height of the building in Dubai is x+745
Taipei's building is 301 feet shorter than Makkah's
so, Taipei's building height is x-301
now, we are given
The combined height of the world's three tallest buildings is 6,360 feet
sum of all three heights must be 6360
[tex]x+745+x-301+x=6360[/tex]
now, we can solve for x
Combine like terms
[tex]3x+745-301=6360[/tex]
[tex]3x+444=6360[/tex]
Subtract both sides by 444
[tex]3x+444-444=6360-444[/tex]
[tex]3x=5916[/tex]
Divide both sides by 3
[tex]\frac{3x}{3}=\frac{5916}{3}[/tex]
[tex]x=1972[/tex]
so,
height of building in Makkah is 1972 feet
the height of the building in Dubai is 1972+745=2717
Taipei's building height is 1972-301=1671
Hence,
height of building in Makkah is 1972 feet
the height of the building in Dubai is 2717 feet
Taipei's building height is 1671 feet..................Answer
