A 29 ft long rope is tied to the top of a flag pole. The rope is staked to the ground 21 ft away from the base of the pole. How tall is the flag pole

The height of the pole is 20ft

Step-by-step explanation:

Let the length of thr flagpole be |AB|.

|AB|=29ft

The distance from the foot of the pole to where the rope is staked, |AC|=21ft

We want to determine the height,|BC| of the pole.

Using Pythagoras theorem,

Hyp²=Opp²+Adj²

29²=|BC|²+21²

|BC|²=29²-21²=841-441=400

|BC|=√400=20ft

Therefore the height of the pole is 20ft.

the answer is b.

step-by-step explanation:

identity property is where 0+whatever number=whatever number. basically 0+ a number.

the answer is a
