The reference angle of an angle is obtained by subtracting the angle with 360n where n is an integer until the resulting angle is below 360. In this case, 780 - 360 is equal to 420. this is still more than 360, hence 420 - 360 is equal to 60. the answer thus is 60 degrees.

Answer:

(x, y) = (2, 2)

Step-by-step explanation:

The graph is attached.

Both equations are in slope-intercept form:

y = mx +b . . . . . . line with slope m and y-intercept b

The graph of the first equation intersects the y-axis at +3, and has a slope (rise/run) of -1/2. That is, it decreases 1 unit for each 2 units to the right.

The graph of the second equation intersects the y-axis at -4, and has a slope of +3. It will increase 3 units for each unit to the right.

The point of intersection of the graphed lines is (2, 2).

The solution is (x, y) = (2, 2).
