Please help me with these, find the missing side. Thank yu only if you know
abruzzese [7]

Answer:

7.48m (3s.f.)

Step-by-step explanation:

Let the missing side be x m.

Applying Pythagoras' Theorem,

x² +5²= 9²

x² +25= 81

x²= 81 -25 <em>(</em><em>-25</em><em> </em><em>on</em><em> </em><em>both</em><em> </em><em>sides</em><em>)</em>

x²= 56

x =  \sqrt{56}

x = 2 \sqrt{14}

x= 7.48 (3 s.f.)

∴ The missing side is 7.48 m (3s.f.)
