-6x+5y=1
6x+4y=-10
_________
9y=-9
---- ----
9 9
y=-1
now substitute (-1) in equation 2 like this.
6x+4(-1)=-10
___________
6x-4=-10
+4 +4
___________
6x=-6
---- ----
6 6
x=-1
X=-1 and Y=-1
Since Ryan is 5 feet tall, we will assume that the height of the cell-phone tower is x + 5.
Since the given is 54 degrees.
Tan 54degrees = x/80(feet)
x=80(tan54)
x=110
To finalize the answer, we will add up the height of the cell-phone tower to the answer.
110 + 5 = 115 feet
So the answer to the question is that the height of the cell-phone tower is 115 ft.
I told ya that his phone is on his way lifestyle
<span>4x + 1 = 6x - 2, Prove: x = 3/2
-4x =-4x
1 =2x-2
-1 =-1
0 =2x-3
0 =2x+(-3)
2/3=2/3
</span><span>3x - 4 = 2(x + 8), Prove: x = 20
3x- 4 =2x+16
+4 =+4
3x =2x+20
-2x =-2x
1x =20
