It's a quadrilateral. So what should be the sum of all four angles?

OpenStudy (anonymous):

360

OpenStudy (nikato):

Correct. And you know one of the angle is right which =90 So set up this equation 80+90+2x+3x=360 Can you solve for x?

OpenStudy (anonymous):

so I would have to add all givens (3x+2x+90+80=360) and solve from there. After getting X by itself, I can multiply it by 3 and get the answer?

OpenStudy (nikato):

Correct! So what would angle T be?

OpenStudy (anonymous):

114

Correct
