Linda scored 35, 47, and 42 points on three tests. how many points should she get on the fourth test to get an average score of 50?

a. 75 points
b. 76 points
c. 77 points
d. 78 points

(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

i believe the correct answer is option 4.principalities were small territories that were run by russian rulers.
