Answer:

Ques 1)  1440°

Ques 2) 4000

Ques 3) 33

Step-by-step explanation:

Ques 1)

The sum of the measures of the angles in degrees of a polygon with 'n' sides is given by: 180×(n - 2).

Now we have to find the sum of the measures the angles of a polygon with 10 sides.

i.e. n=10

Hence the value of the expression 180×(n-2) when n=10 is given by:

180×(10-2)=180×8=1440.

Hence, the sum of measure of the angles of a polygon with 10 sides is: 1440°.

Ques 2)

The Expression 500v gives the number of points a player earns for completing v voyages in video game.

We are asked to find the number of points earned for completing 8 voyages.

i.e. v=8 the value of 500v will be 500×8=4000.

Hence, 4000 points are earned for completing 8 voyages.

Ques 3)

we have to find the value of the question as given in the figure:

7x+y+16 for x=2 and y=3.

Hence, we find the value of the expression:

7×2+3+16=33.

Hence, the value of the expression is 33.

How can i solve this and this and this and this?
Rudik [331]

Answer:

DF = 3 , ∠B = 28° , ∠P = 105° , QR = 11.6 , ∠M=45°,LN = 8.5

Step-by-step explanation:

As ΔABC≅ΔDEF ,

DF = AC and ∠B = ∠E because corresponding parts of congruent triangles are equal.

∴DF = 3 and ∠B= 28°

In the next part,

as ΔLMN≅ΔPQR,

∠P = ∠L , QR = MN , ∠M = ∠Q , LN = PR as corresponding parts of congruent triangles are equal.

∴∠P = 105° , QR = 11.6 , ∠M = 45° , LN = 8.5

HELP I NEED TO FINISH THIS QUESTION TO BETTER UP MY GRADE: FIND THE POINTS WHICH WOULD CORRECTLY DILATE THE ORIGINAL BASE BY A S
larisa86 [58]

The vertex for the points Z', O', N', and E' are shown in the figure which is dilated by factor 2.

<h3>What is geometric transformation?</h3>

It is defined as the change in coordinates and the shape of the geometrical body. It is also referred to as a two-dimensional transformation. In the geometric transformation, changes in the geometry can be possible by rotation, translation, reflection, and glide translation.

We have a two-dimensional figure shown in the picture on a coordinate plane.

From the graph the coordinate point or vertex of the point Z:

Z = (1, 2)

Dilating the above point by scale factor 2

Z' = (2×1, 2×2) = (2, 4)

Similarly, for point E:

E = (3, 5)

E' = (2×3, 2×5) = (6, 10)

Similarly, for point N:

N = (4, 5)

N' = (2×4, 2×5) = (8, 10)

Similarly, for point O:

O = (6, 2)

O' = (2×6, 2×2) = (12, 4)

Thus, the vertex for the points Z', O', N', and E' are shown in the figure which is dilated by factor 2.
