(50-25)/2
25/2
12.5
25+12.5=37.5
B) D) and probably C) I’m not sure
cosec60=2/square root of 3
The complete question in the attached figure
we know that
t<span>he centroid is always 2/3 the distance of each median to each vertex
TW=30
TW=TY+YW
TY=(2/3)*30---------> TY=20
then
YW=TW-TY-----------> YW=30-20-----------> YW=10
the answer is
YW=10</span>
