Find the length of the arc. Round your answer to the nearest tenth.

2.6 to nearest 1/10th.

Step-by-step explanation:

Length of the arc = (30/360) * circumference of the circle

= (1/12) * 2 pi * 5

= 2.618

parallel and congruent

step-by-step explanation:

the movement of translation is linear.   these have the same translation because you are using the same rule for each point of the triangle so you will see the same slope being used to get from a point on the triangle to its image.

same slope!   you should think parallel when you see those 2 word together (well unless it's the same line but it can't be because we are coming from different points here)

congruent! because each point is being moved the same distance.

add all the numbers and check the ones place.

the answer is 486. as the ones place is more than 4, the estimation will be the next 10 ie, 490
