Question 1075587
Draw the figure:
Vertical segment, length y.
Horizontal segment at right angle to bottom of the vertical segment; length x and extend this by 20 more units for length x+20.
Point P is at the end of length x.


{{{system(y/x=tan(58),y/(x+20)=tan(28))}}}
Two equations in x and y.


.
.

Evaluate this:  {{{y=(20*tan(28))/(1-tan(28)/tan(58))}}}
