Please help me find the measures of the sides of the triangle: The ratio of the measures of three sides of a triangle are 1/2:1/3:1/5, and its perimeter is 6.2 centimeters. Given the functions:
f(x)= {(3,5), (2,4), (1,7)}
h(x)= {(3,2), (4,3), (1,6)}
g(x)= sqrt(x-3)
k(x)= x^2=5

determine
1) f(h(3))
2) g(k(x))
3) g(k(7))
4) k(g(x))
