Answer:

35°

Step-by-step explanation:

Since all straight lines have a degree of 180, we can find the measures of the other two angles.

180-85= 95

180-130=50

The sum of the measures of the degrees in a triangle is 180. So if we add m∠A + 95+50 it should equal 180.

We can solve that equation to get the measure of ∠A.

m∠A +145=180

m∠A=35°
