Let , missing value(_)=A
As, it is given that ,
To convert the value of A into Radians,
360°=2 π Radians
So, missing value to the nearest hundredth= 1.26 Radians
Let the segment be represented by AB where A(0,0) = and B(3/4,9/10) =
.
The length of the segment drawn by architect can be calculated using distance formula:
AB =
Similarly, Let the actual end points of segment be AC where A(0,0) = and C(30,36) =
.
The length of the original segment can be calculated using distance formula:
AC =
.
Thus, the actual length is 40 times the length of the segment drawn by the architect.
Thus, the proportion of the model is 1:40
