Answer:

Step-by-step explanation:

From the picture attached,

Two lines are the parallel lines and a third line (transversal line) is intersecting these parallel lines.

m∠2 = 60°

a). m∠1 + m∠2 = 180°

m∠1 + 60° = 180°

m∠1 = 180° - 60°

m∠1 = 120°

b). m∠2 = 60° [Given]

c). m∠2 = m∠8 = 60° [Alternate exterior angles are equal]

Answer:

(a) A'(-2, 1), B'(-4, -3), C'(-7, 0)

Step-by-step explanation:

If X is the center of rotation, the coordinates of point P are transformed like this:

P' = -(P -X) +X

P' = 2X -P

(x, y) ⇒ (2(-5) -x, 2(3) -y)

(x, y) ⇒ (-10-x, 6-y)

Your points are transformed to ...

A(-8, 5) ⇒ (-10-(-8), 6-5) = A'(-2, 1)

B(-6, 9) ⇒ (-10-(-6), 6-9) = B'(-4, -3)

C(-3, 6) ⇒ (-10-(-3), 6-6) = C'(-7, 0)

These coordinates match the first choice.

After 2 hrs, the car has traveled 90 miles....that means the car travels 90/2 = 45 miles per hr. After 7 hrs...the car has traveled 7 * 45 = 315 miles
