cestrela7 [59]

If the figure is in quadrant 2, rotating it 270° (that is, 3 quadrants) counter clockwise will move the figure to the 3rd quadrant, then to the 4th quadrant, then to the 1st quadrant.

So the resulting quadrant is the 1st (Quadrant I).

In the rhombus m<1 =160. What are m<2 and m<3? The diagram isn't drawn to scale

Zolol [24]

A rhombus is a parallelogram with four equal sides and two sets of equal angles.

If the m<1=160°, then the angle opposite (3) would also be 160°.

m<3=160°.

Becuase it is a parallelogram, the sum of the measurment of two angles that share a line would be 180 (supplementary).

m<2 and m<4 is 20°.
