The sum of the measures of the angles of a quadrilateral is 360°. Two of the angles are right angles. One of the remaining two angles is twice the measure of the other. What is the measure of the smallest angle in the quadrilateral? What is the measure of the largest angle?
this was my answer:
So 2 angles are right angles which together = 180
so there is now 180 left from the 360
One of the remaining angles is twice the size of the other, so
x + 2x = 180
3x = 180
x = 60
so one angle = 60 , the other angle = 120
but my teacher says it needs units? UNITS?
