Answer:

  • 120°

Step-by-step explanation:

<u>Diagonal BD of a given rhombus is angle bisector of ∠ADC, so:</u>

  • m∠ADB = m∠CDB

<u>Substitute the values and solve for x:</u>

  • 4x - 12 = 3x + 6
  • 4x - 3x = 6 + 12
  • x = 18

<u>Find the value of ∠ADC:</u>

  • m∠ADC = 2(4*18 - 12) = 120°

Write the equation of the line that is perpendicular to the line y = 2x + 2 and passes through the point (6, 3).
weeeeeb [17]

Answer:

\[y = (-1/2) * x + 6\]

Step-by-step explanation:

Equation of the given line: y=2x+2

Hence the slope of the line is given by 2

Any line which is perpendicular to the given line will have a slope m such that m*2 = -1

Or, \[m = \frac{-1}{2}\]

Only options 2 and 3 satisfy this condition.

The line is also supposed to pass through the point (6,3).

Substituting these values in the option 2:

\[3 = (-1/2) * 6 + 3\]

Or, \[ 3 =0 \] which is false . Hence option 2 is not valid.

Now substituting (6,3) in option 3:

\[3 = (-1/2) * 6 + 6\]

Or, \[ 3 =3 \] which is true . Hence option 3 is the required equation of the line.
