A truth table is a way of organizing information to list out all possible scenarios. We title the first column p for proposition.

Answer: Angle DCE would be 12
Step-by-step explanation:
Assuming that angle BCD is right then just set up equation to equal to 90
4x+10+2x+8=90
then solve
6x+18+90
6x=72
x=12
Analytically show that the equation below represents trigonometric
