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.

Answer:
B: 4 solutions
Step-by-step explanation:
Combining the two equations results in 2x² = 52, or x² = 26.
This equation has two solutions: x = ±√26.
As before, x² = 26. If we substitute 26 for x² in the 1st equation, we get:
26 - 4y² = 16, or 4y² = 10, or y = ±√5/2. Again: two solutions.
If we take x to be +√26, y could be ±√(5/2).
Check: is ( √26, √(5/2) ) a solution of the system?
Subbing these values into the first equation, we get:
26 - 4(5/2) = 16. Is this true?
Then 10 = 10. Yes.
Through three more checks, we find that this system has FOUR solutions.
