The map scale is 6 in : 36 mi
simplify it, divide 6 from both sides
6/6 = 1
36/6 = 6
1 in : 6 mi
To find the amount of inches in 52 miles, divide 52 with 6
52/6 = 8.67 (rounded)
8.67 in should be your answer

We are given that angle C is (9x - 1) degrees, and that this is equal to 64 degrees. Therefore,
9x - 1 = 64
9x = 65
x = 65/9
This means that angle B is (6x + 4) = 6(65/9) + 4 = 47 and 1/3 degrees.
In a cyclic quadrilateral, opposite angles add up to 180 degrees, so angle D + angle B = 180
angle D = 180 - angle B
angle D = 180 - (47 1/3)
angle D = 132 2/3 degrees
