What fraction does the number line show?

The answer is 1/8.

If you count all the spaces you get 8 and you can also see that the dot is on the first line. Hence the answer being 1/8.

1/8

Step-by-step explanation:

There are 8 "slices" between the 0 and the 1 in this graph, so it is safe to assume that the fraction you'll end up with will be something out of 8. The dot on the graph given is resting on the firts line on the graph, or the first portion of eight, so you have 1 out of eight pieces.

m∠5 + m∠3 = m∠1   is true.

m∠5 + m∠6 = 180 is true

m∠2 +m∠3 = m∠6   is true

m∠2 +m∠3 +m∠5 = 180   is true
