Can someone help me? Find the value of X.

OpenStudy (anonymous):

Please explain how to do it. Don't just give me the answer.

The inside angles of the shape with four points, have to sum up to 360 degrees. You can use this to find the angle beside x. Then, this angle and x have to sum up to 180 degrees, since they form a straight line. Solving this will give x

The missing measure of the angle is 130 degrees and then since it forms a straight line, X = 50 degrees?

OpenStudy (anonymous):

Yes

OpenStudy (anonymous):

Sweet, thank you so much.

OpenStudy (anonymous):

X=50 degrees
