A triangle has sides that measure 5 units, 12 units, and 13 units. Is this triangle right triangle.
a

The converse of pythagorean theorem.

Step-by-step explanation:

The converse of pythagorean theorem basically says that if the triangle doesn't equal a² + b² = c², then it is not a right triangle. 5² = 25. 12² = 144. 13² = 169. 144 + 25 = 169. The answer is yes, it is a right triangle.

c

step-by-step explanation:

i think because what else can be a sample of every member

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.
