Question

Interior and Exterior Triangle Angles

plz help

Answer 1

∠ N = 41°

Explanation:

The sum of the 3 angles in a triangle = 180°

Sum the 3 given angles and equate to 180, that is

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

10x + 10 = 180 ( subtract 10 from both sides )

10x = 170 ( divide both sides by 10 )

x = 17

Thus

∠ N = 3x - 10 = 3(17) - 10 = 51 - 10 = 41°
