I need help!
Its not a real question im just practicting!

Look here in a square which is what I imagine that drawing is all the angles are 90 degrees. A rectangle would be knowing two angles is know all of them one way or another so fix your work and you should know the answer

x = 200

Step-by-step explanation:

A rectangle (and any parallelogram) will always equal 360 degrees in angles. Technically, every angle has to equal 90 degrees for it to be a rectangle, just a side note.

Thus, 60 + 30 + 70 + x = 360

Solve for x.

60 + 30 + 70 + x = 360

160 + x = 360

x = 360 - 160

x = 200
