Question

A 15 meter trunk broke and fell against a wall. The base of the tree is 10 meters from the wall. Found the distance from the ground to the top of the tree. Round your answer to the nearest tenth. Identify which trig function you will be using to solve the problem.​

Answer 1

11.2 m

Explanation:

The distance from the ground to the top of the tree = h

Using Pythagoras rule :

Adjacent² = hypotenus² - opposite²

h² = 15² - 10²

h² = 225 - 100

h² = 125

h = Sqrt(125)

h = 11.18

h = 11.2 m to the nearest tenth
