We don't know d. Not Sufficient.

Stmt2: b+c=295

b+f=180

c+g=180

Adding, b+c+f+g=360

295+f+g=360

f+g=65

e+f+g=180

e=180-65= 115

a=115

Sufficient.

I was about to ask how we knew that b+c = 180

Thanks for the explanation.

Posted from my mobile device the sum of the angles in a triangle is 180 degrees. Theorem. If ABC is a triangle then <)ABC + <)BCA + <)CAB = 180 degrees
