The chart is incorrect because it calculates 40% of 34 instead of 40 percent of x (we got 85% for our answer but I'm using x as the unknown number) results in the number of 34.

40% of what number = 34 is equivalent to: 40% × ? = 34
They are supplementary because together they equal 180 B and D are vertical and so are A and C and they are also equal so the answer is D. Supplementary
