Neil wants to join three pieces of metal to form a right triangle which of the following lengths could he use
A.) 4,4 and 8 feet B.) 7.5, 10 and 12.5 feet C.) 9, 11 and 23 feet D.) 6, 12.5 and 96 feet

Option B: 7.5, 10 and 12.5 feet forms a right triangle

Explanation:

Given that neil wants to join three pieces of metal to form a right triangle.

We need to determine the set that forms a right triangle.

Since, we know that the hypotenuse of the triangle is the largest measurement in the triangle.

Thus, let us assume that the largest measurement in the given set is the hypotenuse of the triangle.

Option A: 4,4 and 8 feet

Using the Pythagorean theorem, we have,

Since, both sides of the equation are not equal, then the set 4,4 and 8 feet does not forms a right triangle.

Hence, Option A is not the correct answer.

Option B: 7.5, 10 and 12.5 feet

Using the Pythagorean theorem, we have,

Since, the both sides of the equation are equal, then the set 7.5, 10 and 12.5 feet forms a right triangle.

Hence, Option B is the correct answer.

Option C: 9, 11 and 23 feet

Using the Pythagorean theorem, we have,

Since, both sides of the equation are not equal, then the set 9, 11 and 23 feet does not forms a right triangle.

Hence, Option C is not the correct answer.

Option D: 6, 12.5 and 96 feet

Using the Pythagorean theorem, we have,

Since, both sides of the equation are not equal, then the set 6, 12.5 and 96 feet does not forms a right triangle.

Hence, Option D is not the correct answer.

step-by-step explanation:

consider an orange peel: if you want to try and lay it flat, you have to stretch it, we know exactly how things are being stretched or squashed at any given point. we have many different map projections because each has different patterns of some projections can even preserve certain features of the earth without
