Question

Find the value of side b. Round your answer to the nearest hundredth.

Answer 1

Answer: 2.83

Explanation:

For this question you have to use pythagoras' theorem.

Pythagoras' theorem states that:

c²=a²+b²

So first you put the numbers in:

c²=2²+2²

Then you would find out what 2² is:

2²=4

c²=4+4

c²=8

Then because you just want c (the Hypotenuse) on it's own you have to square root 8.

√8=2.83 (to the nearest hundredth)

Hope this helps :)

Answer 2

2.83

Explanation:

Pathogrean theorem.

(forgive my spelling)

2^2+2^2=b^2

4+4=b^2

8=b^2

rad8=radb^2

rad8 = b
