Question

Radical form. ooooooooooo

Answer 1

Answer:

missing length = 5.74

Step-by-step explanation:

$a^{2} = c^{2} - b^{2}$

$a^{2} = 7^{2} - 4^{2}$

$a^{2} = 49 - 16$

$a^{2} = 33$

$\sqrt{a^{2} } = \sqrt{33}$

$a = 5.74$

Answer 2

Answer:

by using Pythagoras law

h²=p²+b²

7²=4²+b²

b²=49-16

b=√33=5.744

third side is 5.744
