Answer: the numbers were negative so he needed to add the positive numbers to that equation (I think sorry if I’m wrong)
Step-by-step explanation:
Hi how are you today hopefully your well
You multiplique 2×5/2 dont touch the upper 2, then 10/2=5. 2×3/2,and you get 6/2 = 3 , so 5-3= 2
The height of the tree is 60 meters.
Explanation:
Let the height of the tree be x. The tree casts a shadow of
meters and the distance from the top of the tree to the end of the shadow is
meters.
The sides of the triangle are attached in the image below:
Using pythagoras theorem,

Expanding, we get,




Solving the equation using the quadratic formula
, we get,

Simplifying, we have,



Thus,
and 
where the value
is not possible because substituting the value
in
results in negative solution. Which is not possible.
Hence, the value of x is 60.
Thus, The height of the tree is 60 meters.
