15. Determine the values of the unknown variables
Maurinko [17]
For the left-hand triangle we know: (x+7)\°+(3x-18)\°+(x-9)\°=180\°.
Solving for x we have:
5x\°-20\°=180\°
5x\°=200\°
x=40\°
So the angles on the left are: 47,31 and 102 degrees.

On the right we have y\°+(x+21)\°+(x+17)\°=180\°
Substituting known values and solving we get:
y\°+61\°+47\°=180\°
[tex]y=72\°[/tex}
So the angles on the right are, 72, 61 and 47 degrees.

Can someone help me find what the highlighted part came from?
artcher [175]

Answer:

\cos(\frac25\pi) = \frac14(\sqrt5-1) \approx 0.3090

\sin(\frac25\pi) = \sqrt{\frac58 + \frac{\sqrt5}{8}} \approx 0.9511

\cos(2\pi) = 1

The value of \frac{2\pi }{5} radians corresponds to an angle of 180/5 = 72 degrees.

Which expression is equivalent to (2mn)^4/6m^-3 n^-2? Assume m=0 n=0​
Romashka-Z-Leto [24]

Answer:

7m-(7n-18m)

Step-by-step explanation:

m=0, n=0.

8m^7n^6/3 10m^7n^6/3 8m^16n^12/3 m^4n^6/3

-7m-(3n-(8m-4n-10m)

-7m-(3n-(8m-4n+10m))

-7m-(3n-(18m-4n))

-7m-(3n-18m+4n)

-7m-(7n-18m)
