HELP QUICK. I WILL THUMBS UP
Ugo [173]

A diagram would be nice. The quick answer is C.

The first answer makes AE 8 which is twice as long as AC. I don't think the intent of the question is to use an external point.

The second one is also incorrect. This time E is in a place such that it makes AC and AE both equal and that too isn't possible.

The third one is the answer because D and E are both 1/2 the distance between the end point of the line containing them.

D is wrong because E is the midpoint of AC but D is not the midpoint of AB.

Rearranging formula
allochka39001 [22]

Answer:

Arlo's weight = 52.3 kg

Explanation:

Let Arlo be "x"

Then,

Arlo = x

Bert = x+20 (Because Bert is 20 heavier than Arlo)

Cassie = x+20-5 (Because Cassie is 5 lighter than Bert)

Donnie = \frac{x+20}{2} (Because Donnie is half of Bert's weight)

Average = 57

Step by step Calculations:

57 = \frac{(x) + (x+20) + (x+20-5) + (\frac{x+20}{2} )}{4}  (The whole divided by 4 because the total people is 4)

57*4   =  x + x + 20 + x + 20 - 5 + \frac{x+20}{2}

228 = 3x + 35 + \frac{x+20}{2}

228 - 3x - 35 = \frac{x+20}{2}

193 -3x = \frac{x+20}{2}

2(193 - 3x) = x + 20

386 - 6x = x + 20

386 - 20 = x + 6x

366 = 7x

x = \frac{366}{7}

x = 52.3 kg (corrected to 3 significant figures)

Therefore Arlo's weight is 52.3 kg

How can I solve this?
SVETLANKA909090 [29]

Answer:

y is 70° and x is 40 °

Step-by-step explanation:

the triangle has two equal sides as shown on the diagram...so the next angle to 110° which is 70° is equal to y....then by calculation y + x should give us 110° so if y is 70 then x is 40.
