@Narad

Ferredoxin4:

Using CPCTC, we can conclude that D≅A. We can then conclude that (5y-10)°=45°. You can solve from here.

Nicole:

so find y?

Nicole:

@Narad

Narad:

That's the answer

Nicole:

whats the answer

Narad:

\[5y-10=45\]

Nicole:

but I have to find y?

Narad:

Yes, you must solve this equation

Nicole:

okay http://prntscr.com/nzcgd5

Narad:

\[\Delta ABC = \Delta DFE\] \[AB=DF\] \[2x-4=10\] Solve this equation to find x?

Nicole:

okay http://prntscr.com/nzciq0

Narad:

nº3 \[\Delta RSV= \Delta TVS\] \[RV=ST\] \[\frac{ 1 }{ 2}x-1=5\]4 Solve for x?

Narad:

4 has nothing to do

Nicole:

okay http://prntscr.com/nzck14

http://prntscr.com/nzdm4e

Narad:

\[\Delta ABE = \Delta ACD\] \[\frac{ BE }{ CD }=\frac{ AB }{ AC}\] \[\frac{ x }{ 5 }= \frac{ 4 }{ 10}\] and \[\frac{ BE }{ CD }=\frac{ AE }{ AD }\] \[\frac{ x }{ 5} =\frac{ y }{ (y+2) }\] Therefore, \[\frac{ y }{ (y+2) }=\frac{ 4 }{ 10 }\] Solve this equation for y?

Nicole:

last one http://prntscr.com/nzdnai

Narad:

\[\Delta QVS = \Delta RTS\] \[\frac{ VS }{ TS} = \frac{ QV}{ RT }\] \[\frac{ x }{ 12 }=\frac{ 5 }{ 3 }\] Solve this equation for x?
