The graph shows the death rate of the pneumonic plague in Europe during the 1300s. Pie chart of the death rate of the pneumonic plague during the 1300s. The chart shows the plague was 90 percent fatal.

Based on the graph, approximately how many people who got pneumonic plague died from it?

about 1 in 10
about 2 in 10
about 5 in 10
about 9 in 10

D about 9 in 10.

Step-by-step explanation:

90% fatality means that 9 in 10 people who contracted black plague died.

(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
