Question

I need help. I can't get it right...


If angle AOC = 49 degrees, angle BOC = 2x + 10, and angle AOB = 4x - 15, find the degree measure of angle BOC and angle AOB.

I forgot how this one works..
Which Venn diagram is NOT correct?
o Square circle inside Rhombuses Circle
o Rectangles circle inside Squares Circle
o Kites circle inside Quadrilaterals Circle
o Rhombuses circle inside Parallelogram circle

If you want me to draw the diagrams, let me know.
