I am not sure which "x" you are talking about, the one for the third angle or the one in the parentheses representing another angle.
If you are wondering what the value of "x" being the third angle is, the answer is 60° since this is an equilateral triangle and all the angles are equal to 60°.
But I am pretty sure that you are looking for the value of the "x" in the parentheses. To find its value, you need to create an equation and solve it by isolating "x". Since we know that all the angles are equal to 60°, your equation should look like this :
2x - 4 = 60
Add 4 on each side of the equation
2x = 64
Divide each side of the equation by 2
x = 32
There you go! I really hope this helped, if there's anything just let me know! :)
Count the difference of the x values between the two points (the run of the slope) and the difference of the y values between the two points (the rise of the slope). That would get you the rate of change, or slope, of the line.
Let the three apartments be A, B & C
The rent of A is $x
The rent of B is $y
The rent of C is $z
So x + y + z = 1600 .......(1)
Now
Maintenance of A is 20% of x = 0.20x
Maintenance of B is 20% of y = 0.20y
Maintenance of C is 25% of z = 0.25z
0.20x + 0.20y + 0.25z = 345
Multiplying by 100 we get
20x + 20y + 25 z = 34500
Dividing by 5 we get
4x + 4y + 5z = 6900 .......(2)
Monthly fee of A is 10% of x = 0.10x
Monthly fee of B is 20% of y = 0.20 y
Monthly Fee of C is 10% of z = 0.10z
Now
0.10x + 0.20y + 0.10 z= 1820 - 1600
0.10x + 0.20y + 0.10z = 220
Multiplying by 100 we get
10x + 20y + 10z = 22000
Dividing by 10
x + 2y + z = 2200 ....(3)
