100pts: Prove or disprove: If x is a 2 digit number, and y is the number formed by reversing the order of X's digits, then x + y
= 11(x+y).
For example, if x is 54 then y is 45.

Answer:
Disproved
Step-by-step explanation:
We are given the formula and what both variables equal. So, we can solve to see if this is true.
x = 54 and y = 45
54 + 45 = 11(54 + 45)
99 = 11(99)
99 ≠ 1089
Since they don't equal the same, this disproves it.
Best of Luck!
Step-by-step explanation:
If we use this formula then
X is 54 y is 45
54 + 45 = 11(54 + 45)
99 = 11(99)
99 = 1089
= 1089 - 99
= 990

AC is the hypotenuse (H)
x is the opposite (O)
O and H are in sine
sin=O/H
H=O/sin
H=7.9/sin(53)
