Plz a die is rolled. what is the probability of rolling a 2 or a 6? > > also, is this an mutually exclusive or inclusive event? > > also show your work !

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

Which expression shows the sum of the polynomials with like terms grouped together

Plz ( true - false) all triangles have interior angles whose measure sum to 90.
