19. Name four points. 20. Name two line segments.
21. Name three rays.
22. Name two angles.
23. Name the line three ways.

2 angles are acute and right angles

Step-by-step explanation:

acute is less then 90 degrees and a right angles is 90

i will pick c put check it over to be sure

step-by-step explanation:

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.
