9514 1404 393

Answer:

  42.9 ft

Step-by-step explanation:

The relevant trig relation is ...

  Tan = Opposite/Adjacent

where Opposite in this case is the height of the tree, and Adjacent is the distance to the tree.

  tan(47°) = height/(40 ft)

  height = (40 ft)·tan(47°) . . . . . multiply both sides by (40 ft)

  height ≈ 42.9 ft

The tree is about 42.9 feet tall.

What is the value of x?
Usimov [2.4K]

Answer:

All angles in a triangle sum up to 180 degrees.

So, 63+71+x=180 degrees.

You add like terms: 134, and then add x.

134+x=180 degrees.

Minus x from both sides.

180-134=x.

What do you think x is?

How do the symptoms of depression compare to those of attempted suicide?
mestny [16]
The symptoms of depression and suicide are very similar, because most of the people that are depressed sometimes think about doing something to harm themselves. Plus depression causes them to stop eating, starts to be non social etc. The same goes for those who are having thoughts of suicide or have already done it.
