Step-by-step explanation:

x^6

step-by-step explanation:

this is correct because:

x-6=0

0*x=0

so

x^6

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length
