For positive acute angles A and B, it is known that sin A ſ and tan B = 40. Find the value of cos(A + B) in simplest form.

-1/2 +2

step-by-step explanation:

child does not get an education so she can use the molla on junk

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
