What is the surface area of the prism?

△cde maps to △stu with the transformations (x, y) arrowright (x − 2, y − 2) arrowright (3x, 3y) arrowright (x, −y). if cd = a + 1, de = 2a − 1, st = 2b + 3 and tu = b + 6, find the values of a and b. the value of a is and the value of b is .

15 point ! ~ see if you know the answer to both you!

What are the measures of ∠a, ∠b, ∠c and ∠d? explain how to find each of the angle measure.
