Answer 2

Step-by-step explanation:

to find the mode we have to arrange the given numbers in ascending order like this

3, 4, 5, 6,6,6,6,6 9, 10 , 11, 12,12

so the mode of it is 6 & 12

now we have to find the value of A

first find out value of

cos0° = 1 .........(1)

sin 45° = 1/√2

so 2 sin45° = 2 (1/√2)

2 sin45° = √2 ...........(2)

now put

.....(1) &.....(2) in equation :

cos0° + 2sin 45° + sin A = 3

1 + √2 + Sin A = 3

√2 + sin A = 3 -1

sin A = 2 - √2
