Question 1192562
Try to draw the picture exactly as described.

y, how tall the building
x, on the ground how far Danny from the building when angle of elevation 65 degrees


{{{system(x/y=1/tan(65),y/(x+25)=tan(38))}}}


Solve for y.
{{{y=(25*tan(65)tan(38))/(tan(65)-tan(38))}}}------compute with any tool you want.
