Answer 1

1) The correct answer is C.

2) r = √((4 - 1)² + (7 - 3)²) = √(3² + 4²)

= √(9 + 16) = √25 = 5

The correct answer is D.

3) (180°)(5 - 2) = (180°)(3) = 540°

The correct answer is C.

Answer 2

D, D and C

Explanation:

The first one can be seen in the diagram.

For the second one sub in (x,y) = (4,7) into the equation. It will simplify to r² = 25 so r= 5

For the third if the polygon has 5 sides then the sum of interior angles is 180(5-2) = 540
