Mathematics: [math] hey! could you me? brainliest for the first answer!

I can t really help without the amounts being given but I can say that two supplementary angles add up to 180 degrees, so I hope that helps ...

AC is a diameter, so

$(6x+5)^\circ+(5x+3)^\circ+(8x+1)^\circ=180^\circ$

$\implies19x+9=180$

$\implies19x=171$

$\implies x=9$

BD is also a diameter, which makes angles AQB and CQD vertical pairs, hence

$m\angle AQB=m\angle CQD=73^\circ$

Then

TRUE: $m\angle EQD=(5\cdot9+3)^\circ=48^\circ$

TRUE: $m\widehat{CE}=(8\cdot9+1)^\circ+(5\cdot9+3)^\circ=121^\circ$

FALSE: $m\angle CQB=180^\circ+73^\circ=253^\circ$

FALSE: $m\widehat{DCA}=180^\circ+73^\circ=253^\circ$
