Hi!

So we need to know how much smaller ΔDEF is than ΔABC.

See line DF compared to AC. PQ is 1.5 times smaller than DF. That means ΔDEF is 1.5 times smaller than ΔABC.

So to find the length of DE, divide AB by 1.5.

27/1.5 = 18

x=18

The length of DE is 18

Hope this helps! :)

Hello!

These are similar triangles. As you can see, they have the same angle and all corresponding side lengths have the same ratio.

As you can see, the length of AC appears to be 3/2 of DF, it's corresponding side. This means that x is 2/3 of 27.

2/3(27)=18

Therefore, our answer is D) 18.

I hope this helps!

one interior angle of a polygon is equal to 800 and each of the other interior angles are 128 degrees. Find the number of sides
KiRa [710]

Answer:

6

Step-by-step explanation:

Given information:

Interior angle of a polygon cannot be more that 180°.

One interior angle = 80^{\circ}

Other interior angles are  = 128^{\circ}

Let n be the number of sides of the polygon.​

Sum of interior angles is

Sum=80+128(n-1)

Sum=80+128n-128

Combine like terms.

Sum=128n-48           .... (1)

If a polygon have n sides then the sum of interior angles is

Sum=(n-2)180

Sum=180n-360           .... (2)

Equating (1) and (2) we get

180n-360=128n-48

Isolate variable terms.

180n-128n=360-48

52n=312

Divide both sides by 52.

n=\frac{312}{52}

n=6

Therefore the number of sides of the polygon is 6.
