Find the value of x using the measures of the two given adjacent supplementary angles. The figure is not drawn to scale.

x= 42

Step-by-step explanation:

3x+ 54=180

straight angle is 180

So just solve the equation.

subtract 54 on both sides.

126=3x

divide that by 3, and you get 42.

check You answer by multiplying 42 And 3, Which basically Is 126

and then 126+54

which is then 180

I hope this Helps!

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
