Write and solve an equation for the unknown angle in each of the figures I need help with the 2 bottom ones

Find the measures of the complement and the supplement of each angle, m

△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 .

The measure of angle 0 is 600 degrees
