\huge{\sf \left[{x-2y\atop 6x-2z}\:\:\:{4y-3\atop 2y-z}\right]=\left[{-3\atop 4}\:\:\:{5\atop 3}\right]}

Creating equations

\\ \sf\longmapsto x-2y=-3\dots(1)

\\ \sf\longmapsto 4y-3=5\dots(2)

\\ \sf\longmapsto 6x-2z=4\dots(3)

\\ \sf\longmapsto 2y-z=3\dots(3)

  • From eq(2)

\\ \sf\longmapsto 4y-3=5

\\ \sf\longmapsto 4y=5+3

\\ \sf\longmapsto 4y=8

\\ \sf\longmapsto y=\dfrac{8}{4}

\\ \bf\longmapsto y=2

  • Put the value in eq(1)

\\ \sf\longmapsto x-2y=-3

\\ \sf\longmapsto x=-3+2y

\\ \sf\longmapsto x=-3+2(2)

\\ \sf\longmapsto x=-3+4

\\ \bf\longmapsto x=1

  • Put the value in eq(4)

\\ \sf\longmapsto 2y-z=3

\\ \sf\longmapsto z=2y-3

\\ \sf\longmapsto z=2(2)-3

\\ \sf\longmapsto z=4-3

\\ \bf\longmapsto z=1

Which equation can be used to solve for angle A?
lbvjy [14]

C

By the law of sines, \frac{sinA}{a}=\frac{sinB}{b}=\frac{sinC}{c} where A, B, C are the angles and a, b, c are the lengths of the sides opposite their respective angles. In this case, 110^{\circ} is opposite 4.6 and A is opposite 3.2, so \frac{sinA}{3.2}=\frac{sin(110^{\circ})}{4.6}, giving the answer.
