Answer:

  • 100°

Step-by-step explanation:

∠AEC ≅ ∠BED as vertically opposite angles

  • m∠AEC = m∠BED = 1/2(mAC + mBD), angles between intersecting chords

<u>Substitute values and solve for x:</u>

  • 4x = 1/2(120 + 2x)
  • 4x = 60 + x
  • 3x = 60
  • x = 20

<u>Find the measure of AEC:</u>

  • m∠AEC = 4*20 = 80°

<u>AED and AEC form a linear pair hence supplementary:</u>

  • m∠AED = 180° - m∠AEC<u> </u>

<u>Find the measure of ∠AED:</u>

  • m∠AED = 180° - 80° = 100°

Miller's Steakhouse offers 8 side dishes, 5 types of steak, and 4 toppings. How many different smothered steak dinners can be ma
horrorfan [7]

Answer:

1120

Step-by-step explanation:

To find the possible number of steak dinners, you would multiply the number of choices for each part of the dinner. You would used combinations instead of permutations since the order of the toppings chosen or side dishes chosen do not matter. There are 5 choose 1 choices for types of steak, which is just 5. There are 8 choose 3 choices for side dishes, which is 56. There are 4 choose 3 choices for toppings, which is 4. 5*56*4 is 1120, so there are 1120 possible steak dinners.

Can i get some help :
Charra [1.4K]

Answer:

b = \frac{7}{12}

Step-by-step explanation:

b + \frac{2}{3} = 1 \frac{1}{4} ← change to an improper fraction

b + \frac{2}{3} = \frac{5}{4}

Multiply through by 12 ( the LCM of 3 and 4 ) to clear the fractions

12b + 8 = 15 ( subtract 8 from both sides )

12b = 7 ( divide both sides by 12 )

b = \frac{7}{12}
