Find the measure of angle a and angle b. Explain.

b=78 a=102

Step-by-step explanation:

b=78 becasu of z rule and a=103 becuaes 180-78 = 102

a= 102

b = 78° (Corresponding angles are equal)

Step-by-step explanation:

a and b forms a semi circle

angles on a straight line adds up to 180

so if b is equal to 78°

then u will subtract 78 from 180

180-78= 102°

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
