Answer:
x=3/2. & y=5/2
Step-by-step explanation:
5x-3y=0.......(1)
3x-y=2.........(2)
from equation 2: y=3x-2
substitute in equation 1
5x-3(3x-2)=0
5x-9x+6=0
-4x= -6
X=3/2
Y=3(3/2)-2
=5/2
The measure off DF is 11.
In a circle inscribed within a triangle, the distance from each vertex of the triangle to the two nearest touchpoints (points of tangency on the circle) are equal. Since SD=4, DT=4 as well. Since UF=7, then FT=7.
DF=DT+TF=4+7=11.
