Answer:

I think both angles are 95 degrees for question 14

Step-by-step explanation:

Because if you split the shape in half they make two triangles which is always the sum of 180 so all you do is add the two know angles together to get 128. Once you have that you would solve for your missing angles by subtracting 180 from 128 which gives you 95 degrees.

85+ m<b+ 43= 180 degrees goes for angle d to.

83+43=128

180-128=95

Now check work by plug in your answer.

85+95+43=180

180=180

making this a true statement.
