Answer:

Therefore the correct assembling is

3.∠DAC ≅ ∠BCA 3. Alternate interior Angles are Equal as AD || BC.

Step-by-step explanation:

Given:

AD ≅ BC and AD || BC

To Prove:

ABCD is a Parallelogram

Proof:

Alternate Interior Angles Theorem :

"When two parallel lines are cut by a transversal , the resulting alternate interior angles are congruent.

Here AD || BC and the transversal is AC

Statement Reasons

1. AD ≅ BC . 1. Given

2. AD || BC 2. Given

3.∠DAC ≅ ∠BCA 3. Alternate interior Angles are Equal as AD || BC.

Therefore the correct assembling is

3.∠DAC ≅ ∠BCA 3. Alternate interior Angles are Equal as AD || BC.

Answer:

Step-by-step explanation:

When angles are between the parallel lines, they are called interior. If they are both on the same side of the transversal, they are "same-side interior."

If angles are on opposite sides of the transversal, they are exterior.

If angles are in the same direction from the intersection point, they are corresponding.

Angles in opposite directions from the point of intersection are vertical angles.

same-side interior: {3, 5} and {4, 6}. (supplementary)

same-side exterior: {1, 7} and {2, 8}. (supplementary)

alternate interior: {3, 6} and {4, 5}. (congruent)

alternate exterior: {1, 8} and {2, 7}. (congruent)

corresponding: {1, 5}, {2, 6}, {3, 7}, {4, 8}. (congruent)

vertical: {1, 4}, {2, 3}, {5, 8}, {6, 7}. (congruent)

Angles 6 and 4 are same-side interior angles; their sum is 180°.

Ziyad is hoping to start his own lawn care business in Gettysburg, PA. Gettysburg has about 2,400 households. Ziyad went to

Irina-Kira [14]

Answer:

1380 households in Gettysburg are likely interested in using lawn care services

Step-by-step explanation:

To solve this question, we find the sample proportion and estimate for the entire population.

Sample proportion of households in Gettysburg that are likely to be interested in using lawn care services?

92 of 92 + 51 + 17 = 160 households.

92/160 = 0.575

Based on his results, how many households in Gettysburg are likely interested in using lawn care services?

Sample proportion of 0.575.

For the entire population of 2400 households:

0.575*2400 = 1380

1380 households in Gettysburg are likely interested in using lawn care services
