Mathematics
1 answer:
Andreyy893 years ago
3 0

Answer:

The correct answer is A) 7, 10 and 16 inches.

Step-by-step explanation:

The rest of these are Pythagorean triples, which most teachers have you memorize. However, you can also check them using the Pythagorean Theorem.

a^2 + b^2 = c^2

7^2 + 10^2 = 16^2

49 + 100 = 256

149 = 256

Since this is not correct, this is not a right triangle.

Suppose someone tells you that she has a triangle with sides having lengths 2.2, 4.5, and 6.7. Is this a right triangle?
laila [671]
You can apply the Pythagorean theorem:
a^2 + b^2 = c^2
c is the longest side of the triangle
2.2^2 + 4.2^2 = 6.7^2
4.84 + 17.64 = 44.89
22.48 =/= 44.89
That is not a right triangle
