What is the measure of ZXZY?

x = 30

Step-by-step explanation:

Given line m and line n are parallel:

x + 72 = 3x + 12 export like terms to the same side of equation with opposite indicator (- changes to + and + changes to -)

72 - 12 = 3x - x add/subtract like terms

60 = 2x divide both sides by 2

30 = x

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
