Answer:

a + b + c + d = 230

Explanation:

So first, I am going to write down everything that I can find out from the picture.

a + b = 115

c + d + (180 - a) + (180 - b) = 360

Now, I can use a + b = 115 to simplify c + d + (180 - a) + (180 - b) = 360.

c + d + (360 - (a + b)) = 360

c + d + (360 - 115) = 360

c + d +245 = 360

c + d = 115

Now I know that:

a + b = 115

c + d = 115

Now I can find a + b + c + d

a + b + c + d = (a + b) + (c + d) = 115 + 115 = 230

a + b + c + d = 230
