In the figare, Linet Intersects parallel Lines m and n.
Which two angles named below are vertical angles in the figure?

B.

Step-by-step explanation:

<2 and <3 are vertically opposite angles and are also congruent. Both the angles are hence called vertical angles.

30 units^2

step-by-step explanation:

area is l × w

the length is 3

and the width is 10

3 × 10= 30 units squared

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
