Identify the pair of alternate exterior angles

The and are the alternate exterior angles.

Further explanation:

If two parallel lines intersected by a third line called as a transversal line, it froms eight angles as shown in Figure 1.

The eight angles will together form four pairs of corresponding angles.

and constitutes one of the pairs. Corresponding angles are congruent. All angles that have the same position with regards to the parallel lines and the transversal are corresponding pairs.e.g. , , .

Angles that are in the area between the parallel lines like and above are called interior angles whereas the angles that are on the outside of the two parallel lines like and are called exterior angles.

Angles that are on the opposite sides of the transversal are called alternate angles.e.g. .

All the angles that are either exterior pair of angles, interior pair of angles, alternate pair of angles or corresponding pair of angles are all congruent.

From the given figure, it is observed that the and are alternate exterior angles.

Therefore, and are the alternate exterior angles.

your answer is -9

step-by-step explanation:

she will sew have sewn five dresses   and be 1/3 done with the sixth one in an hour.

step-by-step explanation:

3/4 of an hour=45 mins

lucy makes 1 dress per 11.25 minutes

45 mins+11.25 mins=56.25 mins

60 mins- 56.25 mins=3.75 mins

3.75 mins is 1/3 of of 11.25 mins

therefore she the other 1/3 would be part of the hour and she will have sewn 5 dresses and begun the sixth.
