Answer:
Two trapezoids labeled V R A S and B U W D. Sides B U and V R contain one tick mark. Sides B D, U W, V S, and R A each contain two tick marks. Sides A S and W D each contain three tick marks. The angles represented by vertex letters U, B, R, and V each contain two tick marks. The angles represented by vertex letters D, W, S, and A each contain one tick mark.
8k = 4/9
Divide 8 to both sides, or multiply by its reciprocal 1/8:
k = 4/9 * 1/8
k = 4/72
k = 1/18
B because tangent is Opposite/hypotenuse. = 6/8 = 0.75
20 + 1 + .03 + .005 = 21.035
