Answer:
PY = 8
Step-by-step explanation:
Lets run down the other three to show why they're wrong
<em>MY=8</em>
By P.T, that's wrong (PERPENDICULAR)
<em>PM=MY </em>
We can't prove that with the given
XY=42
Again, by P.T., this is false
BTW: You can prove PY=8 by proving XMP congruent to YMP by SAS
F(n+1)=-1/2f(n)
f(n)=-2f(n+1)
given f(1)=120
-2f(1+1)=120
f(2)=-60
f(2)=-2f(2+1)=-60
f(3)=30
f(3)=-2f(3+1)=30
f(4)=-15
f(4)=-2f(4+1)=-15
f(5)=15/2
