What is the sum of the measures of <A and <B?

Option A, 145 degrees

Step-by-step explanation:

Step 1:  Find the angle C

Since 145 plus c equals 180

145 + c - 145 = 180 - 145

c = 35

Step 2:  Find angle A and angle B

Since angle A and angle B have that little curve on them, that means that they are congrunet or the are the same angle.  ALSO, all triangles add up to 180.

Let a represent angles a and b combine

35 + a - 35 = 180 - 35

a = 145

 Option A, 145 degrees
