The wind has blown a tree so that it is growing at a 108° angle with the ground. the top of the tree is 75 ft. from the ground. how tall is the tree?

78.85 ft

Step-by-step explanation:

 Based on the information provided in the exercise, you can draw the right triangle attached, wheree "x" is the height of the tree.

You need to remember the following identity:

By definition:

Then, this is:

In the right triangle shown in the figure, you can identify:

Then, you need to substitute the corresponding values into  :

Now, you can solve for "x":

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540
