Answer :
Answer:
yes it is a right triangle
Step-by-step explanation:
using Pythagoras' identity
a² + b² = c²
a and b are the 2 shorter sides and c is the longest side
here a = 51 , b = 68 and c = 85
substitute these values into the identity and if both sides are equal then the triangle is right
a² + b² = 51² + 68² = 2601 + 4624 = 7225
c² = 85² = 7225
since the identity is true then the triangle is right

Answer:
yes it's a right triangle
Step-by-step explanation:
- A triangle has sides with lengths of 51 inches, 68 inches, and 85 inches. Is it a right triangle?
we check with the Pythagorean theorem, following logic and definition, 51 and 68 are the legs and 85 the hypotenuse
Formula C^2 = a^2 + b^2
51^2 + 68^2 = 85^2
2601 + 4624 = 7225
7225 = 7225
yes it's a right triangle
