283°?

Step-by-step explanation:

360-77=283?

that full whole thing is 360°

Answer:

13

Step-by-step explanation:

ok so angle BGD= 90 vertically opposite angles

angle CGB = 90 ( CGB + CGA = 180 and CGA is 90 so CGB = 180 - 90 = 90)

CGB + BGD = 180

CGB + 90 = 180

Angle EGB = 77 (V.O.A)

NOW angle CGB = 77 + X

so now

CGB + 90 = 180

77 + x + 90 = 180

77 + x = 90

x = 90-77

x= 13
