Each angle of the triangle added together must be equal to 180, so 53+45=98. 180-98=82. So the top angle is 82, the value of x has to be equal to 180-82 which equals 98
I do not know how to show the working out but its 4+6+6
Its wrong for x = 2
y = (3/4) * 2^2 = 3 (NOT 4)
Answer: 
Step-by-step explanation:
For this exercuse you need to analize the information provided. You know that:
1) The height of the replica of the Empire State Building with its antenna spire in Las Vegas is 485 feet.
2) The height of the real Empire State building is 1,454 feet.
Finally, in order to find the ratio of height of the replica to the height of the real Empire State building, its necessary to divide the height of the replica of the Empire State Building by the height of the real Empire State building.
Therefore, trough this procedure you get that the ratio of height of the replica to the height of the real Empire State building is:

(This fraction cannot be reduced)
