You roll a 6-sided number cube. What is the probability that you do not roll a 2?

Given the graph below state whether or not the relation is a function, and give the domain and range.

If angle 2=3x +1 and angle 3=2x +4what is angle 2

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
