Find the measure of each angle. Assume the lines are parallel.

m2 = WHAT °.
m3 = WHAT°.
m4 = WHAT °.
m5 = WHAT °.
m6 = WHAT °.
m7 = WHAT °.
m8 = °.


And the second question i have is the picture with words. the other picture is for the question above. Thanks!

Answer:

Givens


\angle 1 = 113\°

In the image provided we have a pair of parallels lines and a transversal, this setup forms 8 angles which are related in pairs.

Therefore,


\angle 2= 180\° - 113\° = 67\°, by supplementary angles defintion.


\angle 3 = \angle 1 = 113 \°, by corresponding angles definition.


\angle 4 = \angle 2 = 67\°, by supplementary angles.


\angle 5 = \angle 1 = 113\°, by alternate exterior angles.


\angle 6 = \angle 2 = 67\°, by alternate exterior angles.


\angle 7 = \angle 1 = 113\°, by vertical angles definition.


\angle 8 = \angle 2 = 67\°, by vertical angles.

The answer to the second question is 76°, that's the value that makes lines a and b parallel, because that way those angles would be alternate interior angles, which are always congruent when they are formed by a pair of parallels and a transversal.
