PLEASE HELP ME I'M DESPERATE :( Perform the following series of rigid transformations on ∆ABC:

Translate ∆ABC by moving it 5 units to the right and 2 units up.
Draw the line y = -x, and reflect ∆A'B'C' across the line.
Rotate ∆A''B''C'' counterclockwise about the origin by 270°.

Show each transfromation - There should be three triangles and the line of reflection

Given ab and cb are tangents of p, and m =10°. what is the measure of abp?

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.

If a=0.333333 and b=0.55555, what is the value of a+b
