D) x=90, y=43
This is because sides AB and AC are equal so angles B and C are thus both 47.
Also, since both angles BAD and BAC are equal, and x is likely 90, that must be 180-(90+47)=43.

Alberto rode the train 198 miles

Natali5045456 [20]

Answer: Alberto traveled 792 miles as total distance.

Step-by-step explanation:

Since we have given that

Distance rode by the train = 198 miles

Number of times round tip in last month = 4 times

We need to find the total distance that Alberto traveled.

So, Total distance that Alberto traveled is given by

$198\times 4\\\\=792\ miles$

Hence, Alberto traveled 792 miles as total distance.

Solve the equation no calculator 1/5 (x +2)= 1/4 (x + 6)

NeTakaya

First, you need to get rid of the fraction by multiplying both sides by 20 and you would get:

4(x + 2) = 5(x + 6)

Now, you need to get rid of the parenthesis by distributing:

4x + 8 = 5x + 30

Subtract both sides by 5x:

-x + 8 = 30

Subtract both sides by 8:

-x = 22

Now, divide both sides by -1:

x = -22

P.S.: You don't really need a calculator to solve.

Pythagorean theorem to find the side of 16 20

ivann1987 [24]

Answer: 12

Step-by-step explanation:

<em>Although you have not included which value is the hypotenuse or if they are legs, I will assume the hypotenuse is 20, due to the triangle appearing to be a multiple of the standard 3-4-5 triangle.</em>

The pythagorean theorem is a^2+b^2=c^2, where a and b are the legs and c is the hypotenuse. Thus, plug in the values to get:

$16^2+b^2=20^2$

$256+b^2=400$

$b^2=144$

$b=12$
