List the sides of δrst in ascending order (shortest to longest) if: m∠r =x+28°, m∠s = 2x+16°, and m∠t = x+12

  t, r, s

Step-by-step explanation:

The sum of angles is 180°, so you have ...

  (x +28) + (2x +16) + (x +12) = 180

  4x + 56 = 180

  4x = 124

  x = 31

For this value of x, ...

  2x+16 > x+28, so S is the largest angle and "s" is the longest side.

  x +12 < x +28, so T is the smallest angle and "t" is the shortest side.

The sides, shortest to longest, are ... t = RS, r = ST, s = RT.

1/3 + 1/3 ≠ 2/6 because 1/3 alone = 2/6  

step by step explanation:

1/3 + 1/3 = 2/3       2/3=4/6
