Question

Find the unknown length of x
Side-1 =15cm
Side-2 =8cm
Find the third side

Answer 1

here is your answer
=) a^2 +b^2=c^2
=)8^2 +15^2=x^2
=)64+225=x^2
=)289=x^2
=)x=√289
therefore,
x=17

Answer 2

Step-by-step explanation:

$15^{2}+8^{2}=x^{2} \\64+225=x^{2} \\\289=x^{2} \\\sqrt{289} =\sqrt{x} ^{2} \\x=17$

hence the third side is 17 cm
