A pine tree was struck by lightning and fell as shown in the picture above. Which equation could be used to find the length of the fallen part of the tree?

Option C:

 is used to solve the fallen part of the tree.

Solution:

Given data:

One side length = 7 ft

Base length = 15 ft

To find which equation could be used to find the length of the fallen part.

Let the fallen part be x.

The image is look like a right triangle.

Using Pythagoras theorem,

In a right angled triangle, square of the hypotenuse is equal to the sum of the squares of the other two sides.

Taking square root on both sides of the equation.

This equation is used to solve the fallen part.

Option C is the correct answer.

Hence is used to solve the length of the fallen part of the tree.

answer: approximately 206 bones

i hope this u out a branlist and a would be greatly appreciated :

i believe the answer is the polygon, heptagon.
