Solve for the missing variable. Round to the nearest hundredth if necessary.

What is c when b=√11 and a=20

The answer is 20.27

Step-by-step explanation:

Assuming you are talking about the pythagorean theorem, the equation is

a^2 + b^2 = c^2

Plug the values of a and b into the problem and solve.

(20) ^2 + (√11) ^2=c^2

That can be further simplified to

400+11

as 20 * 20 is 400 and √11 * √11 is 11.

Then you add those answers together which equals

411

Remember that 411 is equal to c^2.

To solve for c you have to take the square root of the equation.

√411=√ (c^2)

When simplified √ (c^2) is

20.27313493

Now rounding to the nearest hundredth means the second decimal place is what you round to.

The second decimal place is where the 0.07 is at. 3 is closer to. 07 than to 0.08 so you round down.

The answer is thus 20.27
