A=1/3h (a+4b+c) a=20 h =5 a=1 c=1

Which of the following transformations does not preserve congruence? * 5 points a. (x, y) → (y − 3, x − 3) b. (x, y) → (x + 5, y − 1) c. (x, y) → (y + 9, −x + 2) d. (x, y) → (3x + 1, 3y − 2)

If angle 2=3x +1 and angle 3=2x +4what is angle 2

When y’all answer can y’all explain too !
