mhanifa:
\[32 + x ^{2} = 12x\]
imyoursgirlsgirl:
ok do i combine the x
mhanifa:
Its a quadratic equation, you need to solve
mhanifa:
\[x^2 -12x + 32 = 0\]
imyoursgirlsgirl:
x=8 or x=4

mhanifa:
Ignore x=8 as 12*8=96>90
mhanifa:
So x = 4 is correct one
imyoursgirlsgirl:
thats what i thought
imyoursgirlsgirl:
as just about to say that
mhanifa:
Angle NLP is x^2
