Which equation is equivalent to sqrt x +11=15

x=16

Step-by-step explanation:

We are given that

we have to solve this equation for x

in order to do that we need to isolate x first

hence

subtracting 11 from both sides we get

Now we square on both sides we get

hence x =16

step-by-step explanation:

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
