42°

Step-by-step explanation:

Angle b and angle c are supplementary. That is they have a measure of 180°

Now,

Angle b = -4+4x

Angle c = 16

Therefore

So therefore x= 42°

( And it is already rounded to the nearest tenths )

________________________________

We can even check it!!

As we know that both are supplementary so

As LHS = RHS so the value of x is 42°

Hope it helps you!!

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
