Janae is standing at a distance of 9 feet from the bottom of pole
<em><u>Solution:</u></em>
The flag pole, and the point where Janae is standing and the ground forms a right angled triangle
The figure is attached below
ABC is a right angled triangle
AB is the height of pole
AB = 12 feet
C is the point where Janae is standing
AC is the distance from the top of the pole to a point on the ground where Janae is standing
AC = 15 feet
BC is the distance between bottom of pole and the point on the ground where Janae is standing
We have to find BC
We can use pythagoras theorem for right angled triangle
Pythagorean theorem, states that the square of the length of the hypotenuse is equal to the sum of squares of the lengths of other two sides of the right-angled triangle.
By above definition for right angled angle triangle ABC,
Substituting the values we get,
Thus she is standing at a distance of 9 feet from the bottom of pole
