Question

Find the length of the missing side​

Answer 1

Answer:

x is 5 cm

Step-by-step explanation:

From pythogras theorem:

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

a is x cm

b is 12 cm

c is 13 cm

${x}^{2} + {12}^{2} = {13}^{2} \\ {x}^{2} = {13}^{2} - {12}^{2} \\ {x} = \sqrt{ {13}^{2} - {12}^{2} } \\ x = \sqrt{169 - 144} \\ x = \sqrt{25} \\ x = 5 \: cm$
