In a convex quadrilateral, the measure of the largest angle is twice the measure of the smallest angle, and the other two angles are both right angles. How many degrees are in the largest angle?

The four interior angles will sum to 360“

So call the smallest angle x and the largest angle 2x

So

90 + 90 + x + 2x = 360

180 + 3x = 360 subtract 180 from both sides

3x = 180 divide both sides by 3

x = 60°

And the largest angle = 2 (60°) = 120°
