Answer 1

`\displaystyle √(34)\:units ≈ 5,8\:units`

Explanation:

No matter what happens to the shape, except for dilation, the sise will be the same, so just insert the lengths of the altitude and base into the formula, no matter if it is point D or B because of the Reflexive Property:

`\displaystyle a^2 + b^2 = c^2 \\ \\ 3^2 + 5^2 = c^2 → 9 + 25 = c^2 → 34 = c^2 \\ \\ √(34) = √(c^2) \\ \\ 5,830951895 ≈ c → 5,8 ≈ c`
