Find the cardinal number of each of the following sets. assume the pattern continues in each part a.{15, 16, 17, 93} b. {6, 8, 10, 12, 1006) c. {x{}x= 1, 2, d. {x|x = x+5 and xen a. the cardinal number of (15. 16. 17. 18. 93) is 700

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
