Q=15
-2x^2 + 8 because if you turn it into vertex form and determine
since the triangles are similar
angle DEC = 60 degrees
3 angles inside a triangle equal 180 degrees
BAC = DCE = 64
CBA = EDC = 56
DEC = 180 -56 -64 = 60 degrees
used angle-angle theorem
Answer: 5x 5y
Step-by-step explanation: because of the length
