<h3>Answers: </h3>

Angle 1 and 3:  Vertical Angles

Angle 4 and 8: Corresponding Angles

Angles 4 and 6: Alternate Interior Angles

Angles 3 and 5: Alternate Interior Angles

Angles 7 and 8: Linear Pair

Angles 1 and 7: Alternate Exterior Angles

=================================================

Explanation:

Vertical angles are formed when you cross two lines to form an X shape. The vertical angles are opposite one another in this configuration.

Corresponding angles are ones that show up in the same corner of each four-corner crossing. In the case of angles 4 and 8, both are in the southwest corner of each four-corner crossing.

Alternate interior angles are angles in between parallel lines and on opposite sides of a transversal. Alternate exterior angles are similar, but they are outside the parallel lines.

A linear pair of angles are adjacent and supplementary (meaning they add to 180).

A pile of sand has a weight of 90kg.
Elodia [21]

Answer:

52.5 kg ANS

Step-by-step explanation:

Weight of a pile of sand = 90kg

Ratio of weight of sand in three bags = 2:3:7

Let the weight be 2x kg, 3x kg, 7x kg respectively A.T.Q.

= 2x + 3x +7x = 90

= 12x = 90

= X= 90/12

= X = 7.5 kg

Weight of sand in medium bag =

= 3 × 7.5

= 52.5 kg ANS

I hope this answer is correct
