Answer:
60°
Step-by-step explanation:
There are a couple of ways to think about this.
a) If we rearrange the figure so both angle vertices are in the same place, then the marked angles would overlap. The amount of that overlap is ...
125° +115° -180° = 60°
That is, the smaller angle between the diagonal lines has a measure of 60°. The measure of i is 60°.

b) If we extend the lower horizontal line to the left, as in the attached figure, we see that the external angle of the resulting triangle is an alternate interior angle that is congruent to the one marked 125°. The remote interior angles of the triangle with respect to that angle are "i" and (180° -115°) = 65°.
The exterior angle is the sum of the remote interior angles, so we have ...
125° = i + (180° -115°)
i = 125° +115° -180° = 60° . . . . as above
When you "combine like terms", you are putting together terms that look similar. For example, 4n and n look similar, because they both have an "n". Imagine the n's are apples, and numbers without 'n' are oranges.
If you have 4 apples, and add 1 apple, you have 5 apples, or 5n.
If you have 6 oranges, and take away 2, you have 4 oranges. But, you can't put apples and oranges together, they are 2 different fruits.
So, you're left with 5n+4!

Answer would be 110 because if a figure has 4 angles all it's angle lengths add up to 360°, so since one of the angles is 70° and there is another angle that's identical to it, 70+70= 140, so you have to do 360-140 which gives you 220, and 220/2 = 110°
