Answer:

angle CDE = angle ZED or angle DEC = angle EDZ

Step-by-step explanation:

AAS = angle angle side

We already have angle C is congruent to angle Z and we have the common side DE, so we just need an angle in between angle c and line DE. The 2 angles in between are CDE and ZED . SO if those are congruent to the top ones, the triangle will be congruent because of AAS.

What are the solutions to the equation? b^2 − 10b=39

erik [133]

1)

$b^2-10b=39\\\\(b-5)^2-25=39 \ |+25 \\\\ (b-5)^2=64\\\\(b-5)^2=(\pm 8)^2\\\\ b-5=-8 \ or \ b-5=8 \\\\ b=-3 \ or \ b=13$

2)
-10b = 3b - 13b

$b^2-10b=39\\\\b^2+3b-13b-39=0\\\\b(b+3)-13(b+3)=0\\\\ (b+3)(b-13)=0\\\\ b+3=0\ or \ b-13=0 \\\\ b=-3\ or \ b=13$
