If \text{m}\angle1\ =\ \left(6x+25\right)\degree, m∠1 = (6x+25)°, and \text{m}\angle4\ =\ \left(10x-11\right)\degree, m∠4 = (10x−11)°, find \text{m}\angle1.m∠1.

In the following diagram it is given that dec,ab || dc, ad || eb, and ad is congruent to bc. a)why isn't abc a parallelogram even though it has a pair of parallel sides and a pair of congruent sides b)explain why be must be congruent to bc. further explain what type of triangle this makes triangle abc and what it tells you about angle 1 and angle 2c) finally why must angle 3 be congruent to angle 1? further, explain why we know that angle 3 is congruent to angle 2
