The tangent function has a period of π or 3.14. The period is the point where the graph touches the x-axis. The graph passes through 0 and then π. The next point is 2π. This goes on for the points nπ where n is any whole number.
Answer: x = 40
have: ∠A + ∠B + ∠C + ∠D = 180°
⇔ x + 6 + x + 4 + x +10 + x = 180°
⇔ 4x + 20 = 180
⇔ x = (180 - 20)/4
⇔ x = 160/4 = 40
