1the population in the united states in 2012 was about 3.1 × 108 people. what key strokes on a calculator can be used to find an increase in population of 5%? a 3 . 1 e x 5 b 3 . 1 e 8 x 1 . 5 c 3 . 1 e 8 x 1 . 0 5 d 3 . 1 e 8 x 0 . 9 5

This might be wrong but I think it is C

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

21
