Show that the triangle below is not a right-angled triangle.

Paha777 [63]

Step-by-step explanation:

A right triangle is a triangle in which one of the angles is a 90∘ angle.

$(5x - 8) + (2x - 5) + (2x + 3) = 180 \\ 9x - 10 = 180 \\ 9x = 190 \\ x = \frac{190}{9} \\ x = 21.11$

$(5x - 8) =97.56 \\ (2x - 5) =37.22 \\ (2x + 3) =45.22 \\$

Since None of the angels is 90° , so the triangle is not a right triangle.
