Answer:
50 degrees
Step-by-step explanation:
because it is a parallelogram, angle B = angle D, and angle C = angle A
that means we have 130(2) = 260 degrees that we know.
the total interior angles of a parallelogram = 360
360 - 260 = 100 degrees left. BUT because those are the total amount of angles left, those are angles A and C combined, so you have to divide 100 in half to get the angle A/ angle DAB
100/2 = 50 degrees. hope this helps! leave a question if you are still confused.
Answer:
The correct answer is B.
Step-by-step explanation:
In order to find this, calculate out the discriminant for each of the following equations. If the discriminant is a perfect square, then it can be factored.
Discriminant = b^2 - 4ac
The only of the equations that does not yield a perfect square is B. The work for it is done below for you.
Discriminant = b^2 - 4ac
Discriminant = 7^2 - 4(2)(-5)
Discriminant = 49 + 40
Discriminant = 89
Since 89 is not a perfect square, we cannot factor this.
