Let E be the midpoint of OA and F be the midpoint of OB.
If point O is placed between A and B, then points E and F are placed <span>on different sides from O. The segment OE has length 12÷2=6 cm and segment OF has length 9÷2=4.5 cm. Than EF=6+4.5=10.5 cm.
</span>
If
point O is placed outside the segment AB, then point B is closer to
point O than point A, because OA>OB. Since OE=6 cm and OF=4.5 cm,
EF=6-4.5=1.5 cm.
Since the triangles are congruent and m<I is congruent to m<P.
Therefore, 3x + 4 = 72 - x
3x + x = 72 - 4
4x = 68
x = 68/4 = 17
x = 17
Part A: 680-960d= 52,000
Part B: Answer $54.875
Do inverse operation
Add 680 to both sides
Then divide 960 to both sides
Answer:
The answer is letter D.
