The figure shown on the right illustrates that the numbers 1, 2, 3, 4, 5, and
6 can be placed around a triangle in such away that the three numbers
along any side sum to 9, which is shown in the circled number inside the
triangle. Arrange the numbers 1, 2, 3, 4, 5, and 6 to give the sums circled
in the next three figures.
(a) Determine the numbers for a, b, c, and d for the triangle shown to
the right.
a=\boxed{\hspace{0.5cm}}, b=\boxed{\hspace{0.5cm}}, c=\boxed{\hspace{0.5cm}}, d=\boxed{\hspace{0.5cm}}
(b) Determine the numbers for a, b, c, and d for the triangle shown to
the right.
a=\boxed{\hspace{0.5cm}}, b=\boxed{\hspace{0.5cm}}, c=\boxed{\hspace{0.5cm}}, d=\boxed{\hspace{0.5cm}}
(c) Determine the numbers for a, b, c, and d for the triangle shown to
the right.
a=\boxed{\hspace{0.5cm}}, b=\boxed{\hspace{0.5cm}}, c=\boxed{\hspace{0.5cm}}, d=\boxed{\hspace{0.5cm}}
