Answer:

10 sides

Step-by-step explanation:

(28x+4)°+(5x+11)°=180°

28x+5x+11°+4°=180°

33x+15°=180°

33x=180-15

33x=165°

X=5.

Interior =(28×5)+4=144°

Exterior=(5×5)+11°=36°

No. of sides=360°\exterior

360°\36

10.

Solve the system of equations algebraically. Verify your answer using the graph.
nirvana33 [79]
Both of those equations are solved for y.  So if the first one is equal to y and the second one is equal to y, then the transitive property says that the first one is equal to the second one.  We set them equal to each other and solve for x.  4x-5=-3 and 4x = 2.  That means that x = 1/2.  We were already told that y = -3, so the coordinates for the solution to that system are (1/2, -3), B from above.
