180°(n-2) = 180°(6-2)
= 180°(4)
= 720°
4(3x)+2(2x) = 12x + 4x
= 16x
720° = 16x
45° = x
45°(3) = 135°
Therefore the answer is D.

<h3>Answer: Tony is correct</h3>

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

Explanation:

There are number of ways to go about this, but let's pick on the sides marked in the diagram below (circled in red and blue). I picked on those sides specifically because they are on either side of the marked angles (A and Q).

They help form the proportion below, in which we'll show later on its a false statement.

AE/PQ = AB/QR

24/(14.5) = 18/(11.5)

24*11.5 = 14.5*18

270 = 261

We arrive at a false statement at the end, so the original proportion is false. Furthermore, it means the figures are <u>not</u> similar.

--------------

We could try the other way around and try to see if

AE/QR = AB/PQ

is true or not

Let's find out

24/(11.5) = 18/(14.5)

24*14.5 = 11.5*18

348 = 207

We see this is false as well. The gap is even bigger than before, so the first scenario was slightly close to having similar polygons. But neither case works perfectly. So that's why we don't have similar polygons and why Tony is correct. It's not enough to look at the angles only when dealing with polygons that have more than 3 sides. If we were just focused on triangles, then Jacenta would be correct.

A vehicle travels 250 feet every three seconds find the value of the ratio, the unit rate, and the constant proportionality. How
lidiya [134]

Answer:

The ratio, the unit rate and the constant of proportionality are same but with different name.

Step-by-step explanation:

A vehicle travels 250 feet every three seconds.

(i) So, the ratio is \frac{250}{3}  feet/seconds.

(ii) The unit rate means the rate of change of distance with respect to unit time,

The vehicle in three seconds moves by 250 feet.

Hence, the vehicle in one second will move by \frac{250}{3} feet.

Therefore, the unit rate is \frac{250}{3} feet/seconds.

(iii) The relation between the distance traveled (d) and the time of travel (T) is proportional.

So, D ∝ T, ⇒ D = kT ......... (1) {Where, k is the constant of proportionality}

Since D = 250 feet at T = 3 seconds

So, from equation (1), k = \frac{D}{T} = \frac{250}{3}  feet/seconds.

Therefore, from the above explanation it is clear that the ratio, the unit rate and the constant of proportionality are same but with different name. (Answer)

Describe a single transformation that maps triangle ABC to triangle A"B"C" :)
lyudmila [28]

Answer:

To describe a sequence of transformations that maps triangle ABC onto triangle A"B"C", a student starts with a reflection over the x-axis. The student completes the sequence of transformations to map triangle ABC to triangle A"B"C" by translating the figure 2 units to the right. Translate the figure 6 units up.

Step-by-step explanation:

Lapatulllka [165]

Answer:

A. +95

Step-by-step explanation:

  1. Above = positive
  2. So, 95 feet above sea level = +95
  3. Therefore, A is the correct option
