<PRE><B>Question 1208494</B>
You can draw the described triangle, label the parts, and find the needed equation and solve.



45 ft., vertical side
x, horizontal side
40 degree, opposite angle to the vertical side
50 degree , opposite angle of the x side
90 degree, the base, between the 45 ft. and the x ft.

.

.

Law Of Sines:


{{{sin(40)/45=sin(50)/x}}}


{{{x*sin(40)=45*sin(50)}}}


{{{x=45((sin(50))/(sin(40)))}}}


{{{x=45(0.7660/0.6428)}}}


{{{x=53.6}}}
