PLEASE HELP ASAP!!!

Step-by-step explanation:

5x^2+2x=1

5x^2+2x-1=0

x=-b+/-√b^2-4ac÷2a

x=-2+/-√-2^2-(4×5×-1)÷2×5

x=-2+/+√4--20÷10

x=-2+/-√24÷10

x=-2+√24÷10 or -2-√24÷10

x=-2+4.9÷10 or -2-4.9÷10

x=2.9÷10 or -6.9÷10

x=0.29 or -0.69

R, S, and T are the vertices of one triangle. E, F, and D are the vertices of another triangle. m∠R = 60, m∠S = 80, m∠F = 60, m∠
Vladimir79 [104]
The correct answer is in file attached  
<span>we have<span>
</span>triangle RST<span>
</span><span>m∠R = 60, m∠S = 80  and m∠T=180-(80+60)=40</span></span>
<span>RS=4<span>
</span>triangle EFD<span>
</span><span>m∠F = 60, m∠D = 40  and m∠E=180-(60+40)=80</span></span>
EF=4  
Therefore
  <span>The triangles RST<span>  and </span>EFD are congruents because they have two angles and the side common to them, respectively, equal.
This is the theorem of ASA (angle-side-angle).</span>
Explication
Side common--------> RS=EF
<span>Angles RS------------- > m∠<span>R = 60  m</span>∠S = 80 </span>
<span>Angles EF------------- > m∠<span>E = 80  m</span>∠F = 60 </span>    

<span>The segment which is congruent to RT is FD, because angles of RT are 60 and 40, and angles of FD also are 60 and 40.</span>
