- Parallelogram ABCD is a rhombus. If m<ADC = 42° what is m<ADE?
- Parallelogram ABCD is a rectangle. The mAD= 3x-12, what is mBC if mBC = x + 10?
- Parallelogram ABCD is a square. If m<AEB = 3x-12, find the value of x.

All side =. There's only 4 corners. What is "e"?
Both sets of opposite sides are =.ad=bc; 3x-12=x+10
2x=22
x=11
substitute
3. There's only 4 corners; what does "e" represent?

You need to identify where point E is in the parallelogram for 1 and 3. For 2, you just need to set x + 10 = 3x - 12, solve for x, then plug into the expression for mBC.03/12/21
