Answer:
Solution is
Which is Option C
Step-by-step explanation:
We are given the equations
4x - 6y = 11 ...............(i)
3x+y = 0 ..............(ii)
Now from equation (ii) we have
3x + y = 0
subtracting 3x from both sides we get
3x + y - 3x = 0 - 3x
y = -3x ....................(iii)
substituting this value in equation (i) which is
4x - 6y =11
Putting the value of y
4x - 6(-3x) = 11
4x + 18x = 11
22x = 11
Dividing both sides by 22
we get
or
x=
Now we have equation (iii) which tells us that
y= -3x
Putting value of x here
y = -3()
It becomes
y =
So
Solution set of the equation is

Answer:
the angle of 3 is 50
Step-by-step explanation:
What you would do is add 90 to 40 which would get you 130. Then you will subtract 130 from 180 which gets you 50 for angle 1. Since angle 1 is across from angle 3, angle 3 will also be 50.
