Answer:

3x-20=-6.6 degrees, 7x+10=1.4 degrees

Step-by-step explanation:

You solve each equate separately. So take the equation (3x-20) and solve for x first in that one. so you divide 3 by -20 to get -6.66 degrees for your first angle. Then you solve the other equation. (7x+10) divide 7 by 10 to get the angle measurement. Which would be 1.4 degrees.
