Sort the sequences to whether they are arithmetic, geometric, or neither 1) 98.3 , 94.1 , 89.9 , 85.7 2) 1 ,0 , -1 ,0 3) 1.75 , 3.5 , 7 ,14 4) -1 ,1 , -1 ,1 5) -12, -10.8, -9.6, -8.4

her answer is right but you just have to switch 4 and 5 around 4 is geometric while 5 is arithmetic

step-by-step explanation:

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
