Answer:

x = 2 or 1/4

Step-by-step explanation:

-13/4 -x= 1/2x -1

Collect like terms

-13/4+1=1/2x+x

Using LCM

(-13+4)/4=(1+2x²)/2x

9/4=(1+2x²)/2x

Cross multiply

9(2x)=4(1+2x²)

18x=4+8x²

Turn into quadratic and solve

8x²-18x+4

Using formulae method

-b±(√b²-4ac)/2a

Where a=8, b= -18 and c=4

(-(-18)±(√(-18)²-4(8)(4))/2(8)

(18±(√324-128))/16

(18±√196)/16

(18±14)/16

(18+14)/16 or (18-14)/16

32/16 or 4/16

2 or 1/4

Which quadrant 20 degree in ?
elena55 [62]

Answer:

Therefore 20 degree is in First Quadrant,

i.e Quadrant I.

Step-by-step explanation:

QUADRANT:

When the terminal arm of an angle starts from the x-axis in the anticlockwise direction then the angles are always positive angles.

Quadrant I      -          0° to 90°

Quadrant II     -       90° to 180°

Quadrant III    -      180° to 270°

Quadrant IV    -      270° to 360°

Therefore 20 degree is in First Quadrant, i.e Quadrant I.

When the terminal arm of an angle starts from the x-axis in the clockwise direction than the angles are negative angles.

Quadrant IV  -          0° to -90°

Quadrant III   -       -90° to -180°

Quadrant II    -      -180° to -270°

Quadrant I     -      -270° to -360°
