Answer:
x=0
y= -1
Step-by-step explanation:
x−2y=2 - eq 1
3x+2y=−2 - eq 2
x−2y=2
(3x+2y)+(x−2y)=−2+2
x−2y=2
3x+2y+x−2y=0
x=0
y= -1
Answer:
Angle C
Step-by-step explanation:
By applying sine rule in the given triangle,
![\frac{\text{sinB}}{CD}=\frac{\text{sinC}}{BD}=\frac{\text{sinD}}{BC}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Ctext%7BsinB%7D%7D%7BCD%7D%3D%5Cfrac%7B%5Ctext%7BsinC%7D%7D%7BBD%7D%3D%5Cfrac%7B%5Ctext%7BsinD%7D%7D%7BBC%7D)
![\frac{\text{sinB}}{\text{sinC}}=\frac{\text{CD}}{\text{BD}}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Ctext%7BsinB%7D%7D%7B%5Ctext%7BsinC%7D%7D%3D%5Cfrac%7B%5Ctext%7BCD%7D%7D%7B%5Ctext%7BBD%7D%7D)
Therefore, sides of the given triangle will be in the same ratio as the sine of the angles.
Since, BD > BC > CD
Therefore, Opposite angles of these sides will be in the same ratio.
∠C > ∠D > ∠B
Largest angle of the triangle is angle C.
