PLEASE ANSWER TODAY ASAP WILL GIVE BRAINLIEST TO FIRST TO ANSWER. Angle A and angle B are supplementary angles.

What must be true about the angles?

The sum of the angles is 180°.

The angles were formed by two intersecting lines and are on opposite sides.

The sum of the angles is 90°.

The angles share a common side and vertex.

The sum of the angles is 180°.

Step-by-step explanation:

Supplementary angles are two angles that add up to 180°, look at the example image I have attached.

(4,5

look up a corrdinate plane and do what the thingy says and boom

i leave the calculator work to you.

7. diameter 4 miles, circumference 4π miles

8. radius 0.2 miles, circumference 0.4π miles

[this is a bad problem because the actual radius of a car on the track is less than 0.2 miles so the answer is less than 0.4π miles]

9. radius 6 feet, circumference 12π feet

10. diameter 14 cm, circumference 14π cm

11. diameter 4.8 feet, circumference 4.8π feet
