Question

Can you help me know how to get the answer i don’t need the answers just how to solve the problem

Answer 1

I guess 21

Explanation:

Because if you find the other side by trigonometric theorem-

`x^2 = c^2 - a^2\\x^2 = 12^2 -8^2\\x^2= 144 - 64\\x^2=80\\√(x) =√(80)\\ x=8.94`

which is almost 9

9 is a possible value

they ask you to find the value which doesn't fit in the triangle

so the answer is 21 which doesn't make any sence

Hopefully, the answer would be work
