Hi there!
To find the percent of change we can use the following formula:
Let's fill in our data
Subtract
Divide
And finally multiply
Hence, the percent of change is negative 20%.

Symmetric property, I remembered the answer for this for my summer school. This is one of the equivalence properties of equality.
Answer:
58°
Step-by-step explanation:
A right triangle can be drawn to model the geometry of the problem. The hypotenuse of the triangle is the length of the string, 100 ft. The side opposite the angle is the height of the kite above the ground, 85 ft.
The mnemonic SOH CAH TOA reminds you of the relationship between sides and angles.
Sin = Opposite/Hypotenuse
sin(α) = (85 ft)/(100 ft) = 0.85
The angle whose sine is 0.85 is found using the arcsine (inverse sine) function:
α = arcsin(0.85) ≈ 58.2°
The angle of elevation is about 58°.

When using your calculator to find the values of inverse trig functions, make sure it is in <em>degrees</em> mode. Otherwise, you're likely to get the answer in radians (≈ 1.01599 radians).

Answer:
-14
Step-by-step explanation:
-2(z+11)=6
-2z-22=6
-2z=28
z=-14
