Step-by-step explanation:
I am sure that This one would be c
Note that
108° = 90° + 18°
so
sin(108°) = sin(90° + 18°) = sin(90°) cos(18°) + cos(90°) sin(18°) = cos(18°)
Then
sin²(108°) + sin²(18°) = cos²(18°) + sin²(18°) = 1
by the Pythagorean identity.
49 is a composite number, which means it is divisible by 1, 7, and 49. Hope this helps! :)
