To calculate the total investment in a load fund, B.) MULTIPLY THE NUMBER OF SHARES BY THE OFFER PRICE.
Load fund is a mutual fund. The term "load" is used to refer to a fund with commission.
The commission is the difference of the net asset value and the offer price of the fund.
X=

Or it would be approximately: x≈ 0.37228132, -5.37228132
Hope this helped! ;P
Step-by-step explanation:
multiple possibilities.
e.g.
we could use Pythagoras to get QR, and then use the law of sine to get angle P.
or we can use the law of sine to get angle R, and then use the rule that the sum of all angles in a triangle is always 180° to get angle P.
I propose the second option :
the law of sine :
a/sin(A) = b/sin(B) = c/sin(C)
with a, b, c being the sides always opposite of their associated angles.
33.8/sin(R) = 57.6/sin(90) = 57.6
sin(R) = 33.8/57.6 = 0.586805555...
R = 35.93064691...°
180 = 90 + 35.93064691... + P
P = 54.06935309...°
