Answer:
No
Step-by-step explanation:
In order to solve this you have to use the pythagorean theorem which is [tex]a^{2}[/tex]+[tex]b^{2}[/tex]=[tex]c^{2}[/tex]. So when you do that it becomes [tex]13^{2}[/tex]+[tex]11^{2}[/tex]=[tex]21^{2}[/tex]. 13 x 13 = 169. 11 x 11= 121. If you add those together you get 290. Which means it is not a right triangle because 21 x 21 = 441
