A nest is 15 meters high in a tree. From it’s nest, a bird flies 17 meters to the ground to reach a leaf. How far is the leaf from the base of the tree?

8 metres

Step-by-step explanation:

The nest, leaf and base of the tree are all points that form a right angle triangle.

The longest side is the distance from the nest to the leaf 17 m.

Using Pythagoras Theorem

17² = 15² + (distance from base to leaf)²

289 = 225 + (dist. 4rm base 2 leaf)²

289 - 225 = 64

64 = ( distbase to leaf)²

Square root both sides

Dist from base to leaf = 8 meters

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b

the answer on e2020 was d.
