Name the angle in 2 different ways and name the 2 rays from the diagram below show work

I agree with tclm.
for number 3 remember the definition of a ray which is a point that has a line sticking out of it that doesn't end and doesn't cause the line to follow the definition of a line segment. BT and BN follow this definition .
for number 4 remember that naming angles is pretty much consistent as left to right and right to left. but either way the same letter should be in the center and the same three letters should be involved. so u get KLM and MLK
