2x-3y=0
umka21 [38]

Answer:

Option b (1/2,1/3)

Step-by-step explanation:

we have

2x-3y=0 ------> equation A

4x+6y=4 -----> equation B

Solve the system by elimination

Multiply equation A by 2 both sides

2(2x-3y)=2(0)

4x-6y=0 ------> equation C

Adds eqution B and equation C

4x+6y=4

4x-6y=0

-------------

4x+4x=4+0

8x=4

x=1/2

Find the value of y

2x-3y=0

2(1/2)-3y=0

1-3y=0

3y=1

y=1/3

the solution is the point (1/2,1/3)

=>

        1
      ------ = - 2
      sinΘ

=> sinΘ = - 0.5 => Θ is in the third and fourth quadrant

=> Θ = 180° + 30° = 210°

and Θ = 360° + 30° = 330°

2) tan Θ = √3

=> Θ = 60° and Θ = 180° + 60° = 240°
