Answer: No
Step-by-step explanation:
This triangle is not a right triangle because:
A right triangle must have one side that is exactly 90°.
A triangle with sides 26, 39, and 43 do not have any sides that total 90.
The answer to your question is no.
Best of Luck!
<span>You can use Heron's formula to solve this problem.
</span>

, where
A is the area;
a,b,с are the sides;
s<span> is the </span>semiperimeter<span> of the triangle
</span>

<span>According to conditions:
</span>a = x
b = x+1
с = 2x-1
<span>Calculate the semiperimeter:
</span>

<span>Now we can compose and solve the equation according to Heron's formula:
</span>

<span>As a result, x = 6 is your answer.
I hope this helped.</span>
