Which of the following statements justifies why the triangle shown below is not a right triangle?

answer:

b

step-by-step explanation:

for a triangle to be right

the square of the longest sides must equal the sum of the squares on the other 2 sides, that is

12² = 144

10² + 5² = 100 + 25 = 125 ≠ 144

thus triangle is not right since 5² + 10² ≠ 12² → b

12*c

step-by-step explanation:

the answer is y = 11.54
