Answer:
The length of the sides are 9 units, 18 units and 11 units
Step-by-step explanation:
Let
x ----> one side of the triangle
y ----> the longest side of the triangle
z ----> the third side of the triangle
we know that
The perimeter of triangle is equal to
![P=x+y+z](https://tex.z-dn.net/?f=P%3Dx%2By%2Bz)
we have
![P=38\ units](https://tex.z-dn.net/?f=P%3D38%5C%20units)
so
----> equation A
-----> equation B
----> equation C
substitute equation B and equation C in equation A
solve for y
![y=45(2)/5](https://tex.z-dn.net/?f=y%3D45%282%29%2F5)
![y=18\ units](https://tex.z-dn.net/?f=y%3D18%5C%20units)
<em>Find the value of x</em>
---> ![x=\frac{18}{2}=9\ units](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B18%7D%7B2%7D%3D9%5C%20units)
<em>Find the value of z</em>
----> ![z=18-7=11\ units](https://tex.z-dn.net/?f=z%3D18-7%3D11%5C%20units)
therefore
The length of the sides are 9 units, 18 units and 11 units
