Step-by-step explanation:

there are two ways you can answer this question . the first is you can use tan inverse or calculate the value of hypotenuse using Pythagorean thereom and use sin inverse

1 a*a + b*b = c*c. Pythagorean theroem

2. 6*6 +3*3 = c*c

36+9= c*c

√45 =c or. 3√5 ( when simplified)

sin <R =OPPOSITE

HYPOTENUSE

sin <R = 6/3√5

sin <R= 0.89

<R= sin-1(0.89)

<R= 63°

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
