If the measures of two sides of a triangle are 3.1 feet and 4.6 feet, which is the least possible measure to the nearest tenth for the third side?
a. 1.6 feet
b. 4.6 feet
c. 8 feet
d. 7.5 feet

  a. 1.6 feet

Step-by-step explanation:

The triangle inequality requires the sum of the shortest two sides exceed the longest side. If x represents the shortest side, that means ...

  x + 3.1 > 4.6

  x > 1.5 . . . . . . . subtract 3.1

The smallest answer choice meeting this requirement is 1.6 feet.

Comment on this answer

A measure of 1.5001 feet will satisfy the triangle inequality. That value would round to 1.5 when rounded to the nearest tenth.

The correct answer is 2. for some reason its not listed in choices

fahrenheit

step-by-step explanation:

fahrenheit is more precise than celsius. the ambient temperature on most of the inhabited world ranges from -20 degrees fahrenheit to 110 degrees fahrenheit—a 130-degree range. on the celsius scale, that range is from -28.8 degrees to 43.3 degrees—a 72.1-degree range. this means that you can get a more exact measurement of the air temperature using fahrenheit because it uses almost twice the scale.
