A parallelogram is a type of quadrilateral where opposite sides are parallel and equal in length. In this article, we will explore the properties of parallelograms and how they relate to the angles within them. Specifically, we will examine the given parallelogram LMNO and determine which statements are true about it.

Properties of Parallelograms

A parallelogram has several key properties that can help us understand its angles and sides. Some of these properties include:

  • Opposite sides are parallel: In a parallelogram, opposite sides are always parallel to each other.
  • Opposite sides are equal in length: In a parallelogram, opposite sides are always equal in length.
  • Consecutive angles are supplementary: In a parallelogram, consecutive angles (angles that share a side) are always supplementary, meaning they add up to 180 degrees.
  • Diagonals bisect each other: In a parallelogram, diagonals (lines that connect opposite vertices) bisect each other, meaning they divide each other into two equal parts.

Given Parallelogram LMNO

The given parallelogram LMNO has the following angle measures:

  • ∠M=(11x)∘\angle M = (11x)^{\circ}
  • ∠N=(6xβˆ’7)∘\angle N = (6x-7)^{\circ}

We are asked to determine which statements are true about parallelogram LMNO.

Statement A: x=11x=11

To determine if statement A is true, we need to examine the given angle measures and see if we can find a value of x that satisfies both of them.

Since ∠M\angle M and ∠N\angle N are supplementary, we can set up the following equation:

(11x)∘+(6xβˆ’7)∘=180∘(11x)^{\circ} + (6x-7)^{\circ} = 180^{\circ}

Simplifying the equation, we get:

11x+6xβˆ’7=18011x + 6x - 7 = 180

Combine like terms:

17xβˆ’7=18017x - 7 = 180

Add 7 to both sides:

17x=18717x = 187

Divide both sides by 17:

x=11x = 11

Therefore, statement A is true.

Statement B: m∠L=22∘m \angle L=22^{\circ}

To determine if statement B is true, we need to examine the given angle measures and see if we can find a value of x that satisfies both of them.

Since ∠L\angle L and ∠M\angle M are supplementary, we can set up the following equation:

m∠L+(11x)∘=180∘m \angle L + (11x)^{\circ} = 180^{\circ}

Substitute the value of x from statement A:

m∠L+(11β‹…11)∘=180∘m \angle L + (11 \cdot 11)^{\circ} = 180^{\circ}

Simplify the equation:

m∠L+121∘=180∘m \angle L + 121^{\circ} = 180^{\circ}

Subtract 121 from both sides:

m∠L=59∘m \angle L = 59^{\circ}

Therefore, statement B is false.

Statement C: m∠L+m∠M=180∘m_{\angle} L + m_{\angle} M = 180^{\circ}

To determine if statement C is true, we need to examine the given angle measures and see if we can find a value of x that satisfies both of them.

Since ∠L\angle L and ∠M\angle M are supplementary, we can set up the following equation:

m∠L+(11x)∘=180∘m_{\angle} L + (11x)^{\circ} = 180^{\circ}

Substitute the value of x from statement A:

m∠L+(11β‹…11)∘=180∘m_{\angle} L + (11 \cdot 11)^{\circ} = 180^{\circ}

Simplify the equation:

m∠L+121∘=180∘m_{\angle} L + 121^{\circ} = 180^{\circ}

Subtract 121 from both sides:

m∠L=59∘m_{\angle} L = 59^{\circ}

Therefore, statement C is true.

Conclusion

In conclusion, the true statements about parallelogram LMNO are:

  • x=11x=11
  • m∠L+m∠M=180∘m_{\angle} L + m_{\angle} M = 180^{\circ}

The false statement is:

  • m∠L=22∘m \angle L=22^{\circ}
