If m<2= (2m-20)° and <4= (130-m)°, what is the value of M?

[tex]\\[/tex]

As you can see in the figure, ∠2 and ∠4 are congruent. So that means it has the same measurement. Follow the solution and you will know the value of m.

  • 2m - 20 = 130 - m
  • 2m + m = 130 + 20
  • 3m = 150
  • m = 150/3
  • m = 50

I conclude that the value of m is 50. Let us check if ∠2 and ∠4 are really congruent.

[tex]\\[/tex]

  • 2m - 20 = 130 - m; m = 50
  • 2(50) - 20 = 130 - 50
  • 100 - 20 = 130 - 50
  • 80 = 80 ✔

  • ∴ Therefore, the value of m is B. 50°.
