The coordinate grid above shows a pentagon. the pentagon is translated 1 unit to the left and 10 units down to create a new pentagon.
which rule describes this transformation?
a) (x, y) → (x − 1, y − 10)
b) (x, y) → (x + 1, y − 10)
c) (x, y) → (x − 1, y + 10)
d) (x, y) → (x + 1, y + 10)

The pentagon is translated 1 unit to the left, so the points move to the left by 1 unit. Moving left or right changes the x value, when you move right, the x value increases, when you move left, x decreases. Since x is going left 1 unit:

So x - 1

10 units down. Moving up down or up changes the y value, when you move down, y decreases, when you move up, y increases. Since the pentagon is going down 10 units:

y - 10

Your answer is A

3x + 18 = 147°

step-by-step explanation:

3x + 18 = 147°, because the value of the central angle is equal to the value of the arc formed by it.
