jdoe0001 · Answer

if you were to draw a line from Q to S, would you say what you have "above" is a triangle?

anonymous · Answer

yes

jdoe0001 · Answer

ok, then use the 45-45-90 rule http://www.mathwarehouse.com/geometry/triangles/right-triangles/images/picture-45-45-90-special-right-triangle.gif

anonymous · Answer

its not 45 i already put that and it said its wrong

jdoe0001 · Answer

ok well, they want Q, no "part of Q"

jdoe0001 · Answer

so, 45 is correct for the triangle above, now add the bottom "part of Q"

jdoe0001 · Answer

so, you have a triangle above the QS line, and a rectangle below, the Q angle, as well as the S angle, "overflows" to both the triangle and the rectangle
