35 & 35 are opposite angles ..
A+B+C+D+70=360
A+B+C+D= 290
IMO D

Solution

Given:
• An xy-coordinate plane

To find:
• The value of a + b + c + d

Approach and Working:
• b = 90 – 35 = 55
• a = c = 90
• d + c + 35 = 180
o Implies, d = 180 – 125 = 55

Therefore, a + b + c + d = 90 + 55 + 90 + 55 = 290

Hence, the correct answer is Option D
