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?

30 feet.

Step-by-step explanation:

5/radio tower=5.5/33

radio tower= (33x5)/5.5

radio tower= 30 feet

dilation scale factor 2: starting with δabc, draw the dilation image of the triangle with a center at the origin and a scale factor of two. notice that every coordinate of the original triangle has been multiplied by the scale factor (x2). dilation with scale factor 2, multiply by 2.
