A wire 31ft long is stretched from the top of a flagpole to the ground at a point of a flagpole to the ground at a point 15ft fr
Nat2105 [25]

Answer:the height of the flagpole is 27.12 ft

Step-by-step explanation:

The wire makes an angle with the ground and forms a right angle triangle with the flag pole. The length of the wire represents the hypotenuse of the right angle triangle. The height of the flag pole and the ground distance from the wire represents the adjacent and opposite sides respectively.

To determine the height of the flagpole, x we would apply Pythagoras theorem which is expressed as

Hypotenuse² = opposite side² + adjacent side²

31² = x² + 15²

x² = 961 - 225 = 736

x = √736. = 27.12 ft

What equation could be written for this table?
alexgriva [62]

9514 1404 393

Answer:

  your answer choice is correct

Step-by-step explanation:

The point (0, 3) tells you the y-intercept is 3, eliminating the 2nd and 4th choices.

The table value 3 1/2 for x=1 tells you the slope is 1/2, eliminating the 3rd choice. (y differs by 1/2 when x differs by 1)

The 1st choice is the one that works.
