Answer:
135°
Step-by-step explanation:
The reference angle appears to be about 45°, so a reasonable estimate of the angle size is 180° -45° = 135°.
__
You can do an eyeball comparison with the figure attached to see that the angle is about 135°
This is also the value I see when I place my protractor against the screen.
It is the right answer........
If we multiply the bottom equation by 2 and move x to the right, it becomes:
4y = 2x-38
Now we can substitute it for the 4y in the top equation:
3x + (2x-38) = -23 => 5x = -23+38 => 5x = 15 => x=3
Then 4y = 2*3-38 => y = -8
So the solution is (3,-8)
