Answer:
m∠A and m∠B = 130°
m∠D = 50°
Step-by-step explanation:
If all angles equal 360° and angles A and B are equal then we know the A + D and B + C equal 180° then it's simple subtraction to figure out the degrees of all the angles
Answer:
y ≤ 3x+1
Step-by-step explanation:
when the line is solid with no spaces in between, that automatically rules out A) and C). and the shading is underneath the line so that rules out B) as well. Also, if you look through the line that passes through the Y-axis, you can see that it is on +1 so that automatically tells you that both -1 are out.
Hope this helped you!
