"Write a set of inequalities and solve to find the range of possibilities for x. You will need to write two separate inequalitie
san4es73 [151]

Answer:

  • x > 5/3
  • x < 8

Step-by-step explanation:

<u>First, the side lengths should be greater than zero:</u>

  • 3x - 5 > 0
  • 2x + 3 > 0

Second, The triangles have a common side and the given sides are opposite of 27° and 37° angles.

<u>This tells us the side opposite of greater angle is greater:</u>

  • 2x + 3 > 3x - 5

<u>Simplify each inequality:</u>

  • 3x - 5 > 0 ⇒ 3x > 5 ⇒ x > 5/3
  • 2x + 3 > 0 ⇒ 2x > - 3 ⇒ x > - 3/2
  • 2x + 3 > 3x - 5 ⇒ 3x - 2x < 3 + 5 ⇒ x < 8

<u>Common solution is:</u>

  • x > 5/3
  • x < 8
