Two of it of his favorite buildings are Chicago Sears Tower and the Dubai's Burj Khalifa. If Burji Khalifa stands 830 meters high and Sears tower stands 527 meters high , how much higher is Burji Khalifa than Sears tower

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

something that characterises a right triangle is the fact that we may use pythagoras' theorem to find any one of its sides given that we have the length of the other two sides. here, we have the length of the hypotenuse, √(87) yd, and one other side, √(23) yd, thus we can easily find the length of the remaining side using pythagoras' theorem as defined below:

c^2 = a^2 + b^2, where c is the length of the hypotenuse, and a and b are the lengths of the other two sides.

thus, given that c = √(87) and a = √(23), we may substitute these into the formula we defined above to get:

c^2 = a^2 + b^2

(√87)^2 = (√23)^2 + b^2 (substitute c = √87 and a = √23 into the equation)

87 = 23 + b^2 (evaluate (√87)^2 = 87 and (√23)^2 = 23 - remember that the square root of a number, squared will equal that very same number)

64 = b^2 (subtract 23 from both sides)

√64 = b (take the square root of both sides)

8 = b (evaluate √64 = 8)

therefor, the length of the unknown leg in the right triangle is 8 yd (first answer).

step-by-step explanation:

hans did not square the 40-unit side; he merely multiplied it by 2.   incorrect.
