49 131 90 59

eviant:

those are the answer choices

Vocaloid:

if I understand this correctly, it's saying that angle B and angle BCD are both 90? in that case we can label the angles like so:

Vocaloid:

|dw:1523891844553:dw|

Vocaloid:

|dw:1523891852993:dw|

Vocaloid:

so the sum of the angles in a quadrilateral are 360 angle GHE = ADC = 360 - 90 - 90 - 131 = [if I am understanding this correctly]
