A radio tower casts a shadow 33 feet long. A boy who is 5 feet tall casts a shadow 5.5 feet long. the triangle drawn with a radio tower and its shadow is similar to the triangle drawn with the boy and his shadow. How tall is the radio tower?

Ifound this on google “that means that the graph of a function with direct variation has these features: it is a straight line: because the slope is the ratio y/x = k. it passes through the origin (0,0): because y = kx = k (0) = 0.” i hope this you for what your looking for
