Answer:
7 sqrt(2)
Step-by-step explanation:
We can use trig functions
sin theta = opposite side/ hypotenuse
sin 45 = 7/x
Multiply each side by x
x sin 45 = 7
Divide each side by sin 45
x = 7 / sin 45
x = 7 (sqrt(2) /2)
x = 14 / sqrt(2)
We do not leave square roots in the denominator
x = 14 / sqrt(2) * sqrt(2)/ sqrt(2)
12 sqrt(2)/ 2
= 7 sqrt(2)
Answer:
first try taking the common
Step-by-step explanation:
x(3x+2)=0
3x=-2
x=-2/3
Lines that are parrellell presume to have the same slope.
So if we just calculate the slope of a function or a line we should be good.

Now put in the data from the coordinates of the points 

The form of a function now looks like:
From here we are no longer required to calculate anything more. Leave n alone.
The solutions are the equations of the form above.
That would mean:

Hope this helps.
