The answer is B.16 : 52.
Let's compare all ratios to 4 : 13.
A. In order to be equivalent to 4 : 13 the ratio should be 8 : 26
4 : 13 = (4×2) : (13×2) = 8 : 26
B. In order to be equivalent to 4 : 13 the ratio should be 16 : 52
4 : 13 = (4×4) : (13×4) = 16 : 52 - Thus, this is the right choice.
C. In order to be equivalent to 4 : 13 the ratio should be 12 : 39
4 : 13 = (4×3) : (13×3) = 12 : 39
D. In order to be equivalent to 4 : 13 the ratio should be 20 : 65
4 : 13 = (4×5) : (13×5) = 20 : 65
Z + Y = a right angle so need to equal 90 degrees:
Find Z & Y:
2b + 6 + 3b -1 = 90
5b +5 = 90
5b = 85
b = 85/5
b = 17
Z = 2(17) +6 = 34+6 = 40 degrees
Y = 3(17) - 1 = 51 - 1 = 50 degrees
Y & W make a straight line so need to equal 180:
W = 180 - 50 = 130 degrees.
Z & X make a straight line so need to equal 180:
X = 180 - 40 = 140 degree.
