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.
All we need to do is plug the numbers into the equation.
A:

Not A.
B:

Not B.
C:

C is the correct answer
Answer:
D
Step-by-step explanation:
Sin(45) .70 rounded is 71
Answer:
I am busy but all the questions from 1 to 6 just add the measure of 2 angles which are given and then subtract it from 180, you will get the measure of the remaining angle.
7.
8.: 180/3
