    the sum of the 4 angles inside a quadrilateral is 360 deg it is simple to get the fourth angle since you have the other 3

    @emmalove10gymnast do oyu know how many degrees in a right angle? If so you can answer this question If not then go back to oyu r book or class and find out - THEN this question will be easy for you

    Good So you are told in the question that in the quadrilateral ther are 2 right angles and an angle of 73 deg There are 4 angles in a quadrilateral and I told oyu that the 4 angles add up to 360 deg So there is 1 angle you don't know - let's call it x deg so 2 right angles + 73 deg + x deg = 360 What is x deg?

    360-90-90-73 = 360, 90+90+73+107

    OK good - that is correct So did you know, before you asked this, that the sum of the angles in a quadrilateral was 360?
