Sin (45o) = a / h = a / a sqrt (2) = 1 / sqrt (2) = sqrt (2) / 2 cos (45o) = a / h = a / a sqrt (2) = 1 / sqrt (2) = sqrt (2) / 2

tan (45o) = a / a = 1

csc (45o) = h / a = sqrt (2)

sec (45o) = h / a = sqrt (2)

cot (45o) = a / a = 1

1. is 4 and 2. is 3

step-by-step explanation:

so if you look at the first one you see that 1 is to 4 and 2 is to 8 and so on, so you can see for every 1 there is a times 4 so if it were 3 then it would be 3*4 and it is 12

for number 2 it is 3 because 1 is to 3 and 2 is to 6 so for every 1 there is 3 so if it were 3 then there would be 3*3 = 9

1.5%

step-by-step explanation:

2 is the final ! : )

idk bring the function back   im not smart
