Answer:


Step-by-step explanation:
Solving (47):
To solve for B, we have:
--- sum of angles in a triangle
This gives

Collect like terms


Solving (48):
To solve for Y, we have:
--- sum of angles in a triangle
This gives

Where
-- angle on a straight line
Solve for X


So, we have:



Step-by-step explanation:
Given:
and 
We can solve for f(x) by writing

Let 

Then


We know that f(0) = 0 so we can find the value for k:

Therefore,

M/18 = 24/15
15m = 18 * 24
15m = 432
m = 28.8
