Answer:
We know that in right triangle hypotenuse is the longest side ..
Step-by-step explanation:
so, we find third side by Pythagoras theorem...
Pythagoras theorem = longest side = first side + second side ..
we suppose triangle abc...
so, ac ² = bc² + ab ².
15². = 9² + ab ²
15 ² - 9² = ab ²
225 - 81 = ab ²
ab² = 144
ab ² = ( 12 )²
and now both sides square cancels
ab = 12 cm.
