You place a 50 foot long ladder against the side of a building at an angle of elevation of 55 degrees, how high isthe top of the ladder off of the ground? the top of the ladder off of the ground? show work please

The answer to the system of equation is (2,0)
6x - 3y = 12 --->> 3y = 6x - 12 -->> y = 2 x -4

y = 2x - 4
y = x - 2

In this case we subtract y = x - 2 from y = 2x - 4
So, it would be
y = 2x - 4
-(y = x - 2) --->> -y = -x +2

y = 2x - 4
-y = -x + 2
---------------
0 = x - 2
Now we add 2 to both sides to isolate x

So, x = 2
Now we replace x for two in both equations.

6(2) - 3y = 12
12 - 3y = 12 (I'm distributing)
-3y = 0
3y = 0
y = 0

Now the other equation

y = 2 -2
y = 0

So, the answer is (2,0)

I hope this helps.
YOU'RE WELCOME :D
