Please guys help me l will give you the brainliest if you give me the correct answers. Please show the working.​

180° is galf a full turn, so it takes 1/2 less time that is 20 seconds

90° is 1/4 of a full turm (360°), so it will take (1,4)×40= 10 seconds

45° is 1/8 of 360, so it will take 5 seconds

270° IS 3/4 pf 360°, so the answer is (3/4)×40 = 30 seconds

substitute,

circle 1 = 5

circle 2 = 20

circle 3 = 44

in this case no matter how you add, you will always get a perfect square..

hence proved

happy to
