PLEASE HELP!! A kite is a quadrilateral which has 2 sides next to each other that are congruent and where the other 2 sides are also congruent. Given kite WXYZ, shown that at least one of the diagonals of a kite decomposes kite into 2 congruent triangles.

a. Triangle WYX is congruent to Triangle WYZ by AAA.

b. All of the angles are equal.

c. WZ is congruent to WZ and XY is congruent to YZ. WY is congruent to WY since it is in both triangles.

d. The triangles are not congruent at all

An office supply company conducted a survey before marketing a new paper shredder designed for home use. in the survey, 80 % of the people who tried the shredder were satisfied with it. because of this high satisfaction rate, the company decided to market the new shredder. assume that 80 % of all people are satisfied with this shredder. during a certain month, 100 customers bought this shredder. find the probability that of these 100 customers, the number who are satisfied is 69 or fewer.
