A certain triangle has a 30° angle and a 60° angle. Which must be a true statement about the triangle?
OA. The second-longest side is 3 times as long as the shortest side.
OB. Two sides of the triangle have the same length.
OC. The longest side is twice as long as the second-longest side.
OD. The longest side is 3 times as long as the shortest side.

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

happy to

pls mark as brainliest

i think it might be a but you might want a second opinion

i agree because i see the other persons thinking is clear
