Answer:
m<N = 130°
m<K = 50°
x = 28
Step-by-step explanation:
angle N and angle K are supplementary so the sum of their measures is 180°
4x + 18 + 2x - 6 = 180 add like terms
6x + 12 = 180 subtract 12 from both sides
6x = 168 divide both sides by 6
x = 28 to calculate the measurements of angle N and K replace x with 28
N = 4x + 28 so 4 × 28 + 18 = 130°
N = 2x - 6 and 2×28 - 6 = 50°
