He has half of the money because 1-1/2 = 1/2
See attached picture for better understanding of the problem. In the problem, the given values are the following:
hypotenuse = length of the ladder
adjacent = base of the ladder to base of the wall
Solving the angle x, we have the solution as below:
cos x = adjacent / hypotenuse
cos x = 91 / 350
x = 74.93°
The answer is 74.93°.
Answer:

Step-by-step explanation:
Simplify each term.
EF(g) corresponds HJ(i)
FG(e) corresponds JI(h)
GE(f) corresponds IH(j)
(h/e)*f=(23.4/11.7)*13.05=26.1
Answer C: 26.1
