Part A

As shown, a truss is loaded with forces $P_1=202lb$ and $P_2=401lb$ and has the dimension $a=4\mathrm{.}00ft.$

Determine $A_x$ and $A_y,$ joint A$\text{'}$s reaction forces' magnitudes in the $x$ and $y$ directions, respectively, and $C_y,$ joint C$\text{'}$s reaction force's magnitude in the $y$ direction.

Express your answers numerically in pounds to three significant figures separated by commas.
