Step-by-step explanation:
Assuming that the 270° rotation is in a clockwise motion,
A point (a, b) which undergoes such a rotation will have the new point (-b, a).
Since we have A(2, 1),
A' has the coordinates (-1, 2).
Answer:1 11/20 (I think)
Step-by-step explanation: First subtracting 3 - 2 gets you 1. so we keep that aside and do fractions. first, what do 4 and 5 have in common? They both can be turned to 20. 3/4 can be multiplied to 20 4x5(20) so we do 3x5=15 now you have 15/20. Hope this makes sense. now we do 1/5 to ?/20 5x4=20 1x4=4 so 15/20-4/20=11/20 11/20+1= 1 11/20
-Sorry if its too complicated
(undo ur answer if u trusted me before bc I messed up)
(its good now)

Answer:
58°
Step-by-step explanation:
<MQR = <XQL (vertically opposite angles)
28 + 5b = 70 - 2b
28 - 70 = -2b - 5b
-42 = -7b
-42/-7 = b
6 = b
<MQR = 28 + 5b
= 28 + 5(6)
= 28 + 30
= 58°
