Applying the triangle sum theorem, m∠N = 41°

What is the Triangle Sum Theorem?

Triangle sum theorem states that the sum of the three interior angles of any triangle equals 180°.

Given the following interior angles of ΔMNO:

m∠M = (6x+1)°

m∠N = (3x-10)°

m∠O = (x+19)°

Find the value of x:

m∠M + m∠N + m∠O = 180°

  • Substitute

6x+1 + 3x-10 + x+19 = 180

  • Add like terms

10x + 10 = 180

10x = 180 - 10

10x = 170

  • Divide both sides by 10

x = 17

m∠N = (3x-10)°

  • Plug in the value of x

m∠N = 3(17) - 10

m∠N = 41°
