Answer:

For example: 0=1 This is false because we know zero can't equal one. Therefore we can conclude that the problem has no solution. You can solve this as you would any other equation. 13x−5(x−4)=8x+513x−5x+20=8x+58x+20=8x+58x−8x+20=8x−8x+520=5 We see this is a false statement because 20 does not equal 5.

Check the picture below.

notice the tickmarks, thus TP = PU and TQ = QS, so the PQ segment is then a midsegment of the larger triangle, and thus the angles it makes on the small one, are exactly the same.

zheka24 [161]

Step-by-step explanation:

sina = -√3/2

\cos(a)  =   \sqrt{1 -  { \sin(a) }^{2} }

=  \sqrt{1 -  { (\frac{  - \sqrt{ 3} }{2}) }^{2} }

=  \sqrt{ \frac{4 - 3}{4} }

=  \sqrt{ \frac{1}{4} }

=±1/2

Since, π<a<3π/2

cos a = -1/2

\tan(a )=  \frac{ \sin(a) }{ \cos(a) }

\tan(a )  =  \sqrt{3}
