Question

find the length of the hypotenuse of a right triangle,the other two sides of which measure 9 cm and 12 cm

Answer 1

in right angle... we know a theorem exists.. known as pythagoras theorem which states that
h^2=p^2+b^2
h=hypotenuse
(h^2)=9^2+ 12 ^2
h^2=81+144
h^2=225
h=√225
h=15 cm
therefore hypotenuse =15 CM..... mark as brainliest if helped

Answer 2

${(ab)}^{2} = {(bc)}^{2} + {(ac)}^{2}$
${(ab)}^{2} = {9}^{2} + {12}^{2}$
$ab = \sqrt{81 + 144}$
$ab = \sqrt{225}$
$ab = 15cm$
