3. The total angle is 115, and one chunk of it is 90. Subtracting the two, gives us 25°, which should be the other measure, as m∠ABE and m∠EBC should add up to m∠ABC.

4. Same thing as before. m∠DGJ and m∠JGK should add up to m∠DGK.

Therefore, m∠DGJ is 70 - 40 = 30°.

5. When two 45° angles are put together, it will be 90°, or as it is usually called, a right angle.

Answer:

Solution: (3, 2)

Step-by-step explanation:

It's easier to graph when the equation of the lines are in their slope-intercept form, y = mx + b.

x - 3y = -3

-3y = -x - 3

Divide both sides by -3:

$\frac{-3y}{-3} = \frac{-x - 3}{-3}$

y = 1/3x + 1

where slope = 1/3

y-intercept = 1

x + y = 5

Subtract x from both sides to isolate y:

x - x + y = - x + 5

y = -x + 5

where slope = -1

y-intercept, 5

I started by graphing the y-intercepts of each line. Then, I used the slope of each linear equation (rise over run) to plot the next points on the graph. In the attached screenshot of the graph, x - 3y = -3 is the blue line, while x + y = 5 is the green line. Their intersection occurs at point, (3, 2).

Therefore, the solution is (3, 2).
