Answer:
The length of missing side of triangle is 13 cm.
Step-by-step explanation:
Solution :
Here, we have given that the two sides of triangle are 5 cm and 12 cm.
Finding the third side of triangle by pythagoras theorem formula :
[tex]{\longrightarrow{\pmb{\sf{{(c)}^{2} = {(a)}^{2} + {(b)}^{2}}}}}[/tex]
- [tex]\pink\star[/tex] a = 5 cm
- [tex]\pink\star[/tex] b = 12 cm
- [tex]\pink\star[/tex] c = ?
Substituting all the given values in the formula to find the third side of triangle :
[tex]\begin{gathered}\qquad{\longrightarrow{\sf{{(c)}^{2} = {(a)}^{2} + {(b)}^{2}}}}\\\\\qquad{\longrightarrow{\sf{{(c)}^{2} = {(5)}^{2} + {(12)}^{2}}}}\\\\\qquad{\longrightarrow{\sf{{(c)}^{2} = {(5 \times 5)} + {(12 \times 12)}}}}\\\\\qquad{\longrightarrow{\sf{{(c)}^{2} = {(25)} + {(144)}}}}\\\\\qquad{\longrightarrow{\sf{{(c)}^{2} = 25 + 144}}}\\\\\qquad{\longrightarrow{\sf{{(c)}^{2} = 169}}}\\\\\qquad{\longrightarrow{\sf{c= \sqrt{169}}}}\\\\\qquad{\longrightarrow{\sf{c= \sqrt{13 \times 13}}}}\\\\\qquad{\longrightarrow{\sf{c= 13 \: cm}}}\\\\ \qquad\star{\underline{\boxed{\sf{\red{c= 13 \: cm}}}}}\end{gathered}[/tex]
Hence, the length of missing side is 13 cm.
