Need help ASAP can figure out

Answer is D

Step-by-step explanation:

First use sine to figure out x

so "sin(31) = 12 ÷ x"

mulitply both sides by x and you get "x * sin(31) = 12"

divide both side by sin(31) so you get "x = 12 ÷ sin(31)"

after plugging it in a calculator, you get 23.2992 and just rounf to the nearest tenth and you get 23.3

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
