The dimensions of one of the sails on a sailboat are 9 feet, 12 feet, and 15 feet. Is the sail a right triangle?
kipiarov [429]

Answer:

yes

Step-by-step explanation:

Using the converse of Pythagoras' identity

If the square of the longest side is equal to the sum of the squares of the other 2 sides then the triangle is right.

longest side = 15 , then 15² = 225

9² + 12² = 81 + 144 = 225

Thus the sail is a right triangle.

Misha Larkins [42]

A bag of potatoes weighs 9.42 pounds on a weighing scale.

2. If there is no decimal point, the rightmost non zero digit is the least significant digit.

3. If there is a decimal point, the rightmost digits is the least significant digit even if it is a zero.
