Answer:
Missing side: 6.5 cm
Perimeter: 15 cm
Explanation:
The Pythagorean Theorem says that:
So, we can calculate the missing side of the triangle as:
[tex]c=\sqrt[]{6^2+2.5^2}[/tex]
Then, solving for c, we get:
[tex]\begin{gathered} c=\sqrt[]{36+6.25} \\ c=\sqrt[]{42.25} \\ c=6.5 \end{gathered}[/tex]
Therefore, the perimeter is the sum of the length of the side and it is equal to:
Perimeter = 6 cm + 2.5 cm + 6.5 cm
Perimeter = 15 cm
So, the missing side has 6.5 cm and the perimeter is 15 cm
