sorry it was $1.63
Divide the overal height at the back of the triangle by 2 and subtract this amount from the triangle high, this will give you the exact midpoint of the triangle.then project the original measurement (from the height at the back of the triangle) down from the midpoint
overall height $1.79
midpoint of triangle $3.42
downside target is $3.42-$1.79 = $1.63
