Problema Solution
a geometric pattern is made using 17 triangles and squares. if the triangles and squares have a total of 64 sides, how many triangles were used?
Answer provided by our tutors
let
t = the number of triangles used
s = the number of squares used
a geometric pattern is made using 17 triangles and squares
s + t = 17
the triangles and squares have a total of 64 sides
4s + 3t = 64
by solving the system of equations
s + t = 17
4s + 3t = 64
we find
s = 13 squares
t = 4 triangles
