Answer:
The length of missing side b is 3.5ft.
Step-by-step explanation:
Given:
The legs of the triangle are a= 12 ft, b= ? and the hypotenuse c = 12.5 ft.
Now, we have to find the b which is the one side of triangle.
By using pythagoras theorem we get the value of b:
[tex]a^{2} +b^{2}=c^{2}[/tex]
[tex]12^{2}+b^{2}=12.5^{2}[/tex]
[tex]144+b^{2}= 156.25[/tex]
By subtracting both sides by 144 we get:
[tex]b^{2} = 12.25[/tex]
Using square root both the sides we get:
[tex]b=3.50[/tex]
As we see 0 in the place of hundredth and 5 in the place of tenth so rounding 3.50 to nearest tenth will give 3.5 .
So, b=3.5 ft.
Therefore, the length of missing side b is 3.5ft.
