Anna and Brad are arguing over a problem related to complementary angles. One angle is 30 degrees. The other angle is 2x+10 degrees. Anna thinks the answer is x=25 and Brad thinks it is x=70. Who is correct?
Who is Anna?
Why?
Anna knows complementary angles are 90 degrees. She does her math correctly.
Brad confuses supplementary angles and complementary angles and thinks the total should be 180 degrees.

Is a rectangle a square or is a square a rectangle? Explain.
A square is a rectangle.
Example explanation: A rectangle has opposite sides equal, 4 right angles, and opposite sides are parallel. A square is a special case since it fits all of the above properties AND because ALL sides are equal.
