Answer:

<h3>#2</h3>

<u>CD  ║ EF and ED is transversal, hence </u>

  • ∠CDE ≅ ∠FED ⇒ m∠CDE = m∠FED ⇒ m∠CDE = 28° as alternate interior angles
  • m∠CDB = 160° - 28° = 132°

<u>We can see that:</u>

  • m∠CDB + m∠ABD = 132° + 48° = 180°

Since the angles CDB and ADB sum to 180, these are consecutive interior angles, therefore AB and CD are parallel lines.

<h3>#3</h3>

<u>PU and QT are parallel and PT is transversal, therefore:</u>

  • ∠UPT ≅ ∠QTP as alternate interior angles
  • m∠UPT = m∠QTP = 42° or x = 42°

<u>Now find the missing angles of ΔQTP</u>

  • x + 40° = 42° + 40° = 82°
  • y = 180° - (42° + 82°) = 56°

<u>Now, we see that:</u>

  • m∠TPQ = 82°
  • m∠SQR = 82°

As  ∠TPQ ≅ ∠SQR  these angles are corresponding angles.

Therefore PT and SQ are parallel lines.

Gary ordered 30 pizzas for a party. 60% of the pizzas have 12 slices each. The remaining 40% of the pizzas have 10 slices each.
LekaFEV [45]

Answer:

336 total slices

Step-by-step explanation:

60% of 30 = 18

18 * 12 = 216


40% of 30 = 12

12 * 10 = 120


216 + 120 = 336

David has a bag of coins. The bag contains 7 dimes, 2 nickels, and 6 pennies. He will randomly select 2 coins from the bag one a
luda_lava [24]

Answer:

7/15 for dime

6/15 for pennies

Step-by-step explanation:

7/15 because 7+2+6=15 and there are 7 dimes so 7/15.

6/15 because there are 15 coins and there are 6 pennies so 6/15.

15 is the total so 7 and 6 have to go over it.
