Question

Find the length of the third side to the nearest tenth

Answer 1

√18 ≈ 4.2

Explanation:

Pythagorean theorem:

a² + b² = c²

a = 3

b = 3

So,

3² + 3² = c²

9 + 9 = c²

18 = c²

√18 = c

Answer 2

Answer: 4.2 Units

Explanation:

You use the Pythagorean Theorem and do a^2 + b^2 = c^2

The hypotenuse or the longest side is the c^2

Therefore:

3^2 + 3^2 = c^2

9 + 9 = c^2

18 = C^2

`√(18)` =
`√(C^2)`

About 4.2 units or -4.2 units, However, a side length can't be negative, so the answer is 4.2 Units
