The sum of three consecutive odd numbers is 243.what are the numbers?

79, 81, and 83

Step-by-step explanation:

the sum of three consecutive odd numbers is the same as the sum of the middle one used three times .

243÷3=81, that's the middle one

81-2=79, that's the first one

81+2=83 , that's the third one

Hope this helps.

{79, 81, 83}

Step-by-step explanation:

Represent these consecutive odd numbers by x, x + 2, x + 4.

Their sum is x + x + 2 + x + 4 = 243.

Combining like terms, we get:

3x + 6 = 243, or

3x = 237

Dividing both sides by 3, we get:

x = 237/3 = 79

Thus, the first number is 79, the next is 79+2, or 81, and the last is 81 + 2, or 83:  {79, 81, 83}

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.
