Determine the constant multiplier for each description

12+3b -1=-5-b -12-1+5=-b-3b -8=-4b

(x) - (y) = (1 + 4i)

(3 + 6i) - (2 + 2i) = (1 + 4i)

If two sides of a triangle are congruent, then the angles opposite those sides are congruent. the converse of the base angles theorem, states that if two angles of a triangle are congruent, then sides opposite those angles are congruent.
