Hmmm?... If the Mango tree is supported by a wire anchored in the ground9 feet from its base. The wire is 3 feet longer than the height that it reaches on the tree. Now, I am going to find the length of the wire that we will be needing.
Lolo Dad what are you doing there?
Nothing , I'm just thinking about something. Let's now walk around.
Because it forms a right triangle I will use the Pythagorean Theorem.
Oh Lolo Dad is over there!
(a) 9 ft
I think that is the thing that he is thinking earlier.
The wire is 3 ft longer than the height that it reaches on the tree so 3 ft+ 12 ft is 15 ft.Therefore the length of the wire is 15ft.
c^2=a^2+b^2(x+3)^2=(9)^2 + X^2(x+3)(x+3) = 81+ x^2x2+6x+9=81+x^26x=81-9 6x= 72(divide both sides by 6)x= 12
Jake, the speed of my big truck is 4x+4 m/s.
You are amazing Lolo Dad. How did you know that? Now I know what is the speed of your big truck so I will not wonder anymore.
You are also good in solving like me. Don't you worry my employees will handle the problem about the Mango tree, I'm really sure that they can save the tree.
Oh that is the Mango tree that both of you are talking about.
You know Lolo Dad, me and Melinda always go here when we are a child just to eat Mango.
Lolo Dad the length of the wire that we will be needing is 15 feet.
I know that. I also remember that you also love to play here.
Thank you Lolo Dad. We need to go home now. Me and Jake will meet the land Surveyor.
The Land surveyor is the only one who knows where is the location of the island because that is a surprise from their parents.
Good day sir! Where is our meeting place?
Our meeting place is near the lighthouse. See you there!
They have arrived home.
I think that is familiar to me.
Melinda and Jake going to lighthouse to meet the land surveyor.
That is a good idea Lolo Dad. Okay, I will measure the length of the wire.
