Thirteen plus seven is twenty. One fourth of twenty is five.
The answer is five.
For this case, the first thing you should know is that by definition, the vertical angles are congruent.
We have then:
∠1 and ∠2 are vertical angles.
Therefore, by definition:
∠1 = ∠2
On the other hand we have:
∠2 has a measure of 31 °.
Thus:
∠1 = ∠2 = 31 °
Answer:
the measure of ∠1 is:
∠1 = 31 °
You probably know that for 
, we have
Your sum starts at 
, so it's equivalent to
so the answer is A.
