Question

Radical form. ooooooooooo

Answer 1

missing length = 5.74

Explanation:

`a^(2) = c^(2) - b^(2)`

`a^(2) = 7^(2) - 4^(2)`

`a^(2) = 49 - 16`

`a^(2) = 33`

`\sqrt{a^(2) } = √(33)`

`a = 5.74`

Answer 2

by using Pythagoras law

h²=p²+b²

7²=4²+b²

b²=49-16

b=√33=5.744

third side is 5.744
