Answer:

20

Step-by-step explanation:

Given:

  • m∠JKL = 3x + 5

As per the picture:

  • m∠JKL = m∠JKM + m∠MKL = 45 + x

Comparing the two equations above:

  • 3x+5 = 45 + x
  • 3x - x = 45 - 5
  • 2x = 40
  • x = 40/2
  • x = 20

x = 20 is the correct answer for this question

Otherwise something is wrong with the question.
