Answer:

x = - 3

y = 5

Step-by-step explanation:

x + y =2

x - y = -8

Cancel out both y's. Add x's and whole numbers to find x.

2x = - 6

Divide.

x = - 3

Insert - 3 into one of the equations. Solve for y.

- 3 + y = 2

Cancel out - 3 by adding 3 to both sides.

y = 2 + 3

Simplify.

y = 5

Question 4.

Answer:

  9.80 m

Step-by-step explanation:

The mnemonic SOH CAH TOA is intended to remind you of the relationship between sides of a right triangle and its angles.

__

<h3>setup</h3>

The geometry of this problem can be modeled by a right triangle, so these relations apply. We are given an angle and adjacent side, and asked for the opposite side, so the relation of interest is ...

  Tan = Opposite/Adjacent

Using the given values, we have ...

  tan(24°) = AC/AB = (tree height)/(distance from tree)

  tan(24°) = AC/(22 m)

<h3>solution</h3>

Multiplying by 22 m gives ...

  tree height = AC = (22 m)·tan(24°) ≈ 9.79503 m

The height of the tree is about 9.80 meters.
