What comes next in the pattern?
13, 24, 17, 29, 21, 34, 25, 39,
29, 44, 33, ? ,

49. The pattern is every time you add, you add the next positive number number and every time you subtract, you add the next negative number.

Step-by-step explanation:

13 + 11 = 24

24 - 7 = 17

17 + 12 = 29

29 - 8 = 21

21 + 13 = 34

34 - 9 = 25

25 + 14 = 39

39 - 10 = 29

29 + 15 = 44

44 - 11 = 33

33 + 16 = 49

step-by-step explanation: yes

(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
