A because your not dividing it by 5 your subtracting 5 from k divided by 2
32=2*2*2*2*2=2^5
80=2*2*2*2*5
hcf = 2*2*2*2=2⁴=16
X equals 6
How? Well first I multiplied 12 x 18 which is 216.
Then I subtracted 468 - 216 that equals 252.
Because I know that 2 x 6 equals a 12.....x had to be a 6.
So I multiplied 42 x 6 and it equaled 252.
So x is 6
Sin x = 7/12
x = arcsin (7/12) = 35.69°
