Matthew is five feet tall. He is standing next to a flagpole on a sunny day. Matthew's shadow is three feet long. At the same time, the shadow of the flagpole is 15 feet long. How tall is the flagpole? (Express answer in feet and inches.) ANSWER ASAP I NEED IT BY 2 PM (if you show work and it is the right answer i will give you brainliest)

The pole is 17 feet long

Step-by-step explanation: If Matthew's shadow is 2 feet smaller than his actually size, the shadow of the pole will also be reduced. Since the pole's shadow is 15 feet long, adding 2 will give you its original size, 17 feet.

reduce the friction between its moving parts
