Answer:

angle A: 87°

Step-by-step explanation:

Both the sides: A and C are same to each other. let the angle be x

Find the total interior angle of a polygon with 4 sides:

(n-2)*180

(4-2)*180

360°

when all angles sum up, they equal to 360°

so:

115° + 71° + 2x = 360°

186° + 2x = 360°

2x = 174°

x = 87°
