Answer: 303 meters

Step-by-step explanation:

The Burji Khalifa is 830 meters in height and the Sears tower is 527 meters in height.

To find out how much higher the Burji Khalifa is than the Sears tower, subtract the height of the Sears tower from the height of the Burji Khalifa:

= 830 - 527

= 303 meters

$6\sqrt2$

Why?

We have the isosceles right triangle. The length of legs are 6. Use the Pythagorean theorem:

$h^2=6^2+6^2\\\\h^2=36+36\\\\h^2=36\cdot2\to h=\sqrt{36\cdot2}\\\\h=\sqrt{36}\cdot\sqrt2\\\\h=6\sqrt2$

In general, the formula for calculating the hypotenuse in an isosceles right triangle is $h=a\sqrt2$

a - a leg, h - a hypotenuse
