The missing side length should be 22. Add 13.5 to 14.5 and you should get 28. Subtract 28 from the total perimeter (50) to get 22.

Tell whether the triangle with the given side lengths is a right triangle.

harina [27]

Answer:

It is a right triangle

Step-by-step explanation:

Let,

Base of the triangle = b = 10.5 feet

Hypotenuse of the triangle= h = 14.5 feet

Perpendicular of the triangle = p = 10 feet

According to Pythagoras theorem;

$h^{2}=p^{2} +b^{2}$

$14.5^{2}=10^{2} +10.5^{2}$

$210.25=100+110.25$

$210.25=210.25$

As both side is equal, so it is a right triangle.
