interior angle of that polygon.

Answers

Answer 1

Answer:

12 sides and measure of each interior angle is 150...

Answer 2

Answer:

Step-by-step explanation:

Number of sides = 360°/30° = 12

9 - 2x

Step-by-step explanation:

since there is no equal symbol in this equation, you can only simplify it.

[tex]20-2x-11[/tex]

first combine like terms:

[tex](20-11)-2x[/tex]

then subtract 11 from 20, this will give you 20-2x-11 in its simplest form.

The lengths of two sides of a triangle are given.
Find the range of possible lengths for the third side. 17 cm and 12 cm

Answers

Answer:

Range = 5 - 29

Step-by-step explanation:

a + b > c

a+c > b

c+b > a  

so

17+ 12 > c  ,,,,,,,,,,,,,,,,,,,,,,,,,,,, so it should be lesser than 17+12 which is 29

17 +c > 12    ,,,,,,,,,,,,,,,,,,,,,,,,, and it should be greater than 17- 12 = 5  

c+12 > 17 ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, same here,  it should be greater than 17- 12 = 5  

So the range is ,

17 + 12

to

17-12

In BCD, H is the centroid. If DE=51 find HE.

Answers

Answer:

[tex]HE=17[/tex] units.

Step-by-step explanation:

In a triangle, centroid is the intersecting point of the medians.

Centroid divides each of the medians in ratio [tex]2:1[/tex]

So,

[tex]\frac{DH}{HE}=\frac{2}{1} \\\\\frac{DH}{HE}+1=\frac{2}{1}+1\\\\ \frac{DH+HE}{HE} =3\\\\\frac{DE}{HE}=3[/tex]

Put [tex]DE=51[/tex] units

[tex]\frac{51}{HE}=3\\\\HE=\frac{51}{3}[/tex]

[tex]HE=17[/tex] units.

The triangles are similar . What is the value of X

Answers

Answer:

16

Step-by-step explanation:

There are 2 different ways to solve this

1) The bigger triangle is 4 times bigger than the smaller one

5 x 4 = 20

3 x 4 = 12

From this method you can see they all connect so you take the smaller triangles value of 4 and multiply it by 4

4 x 4 = 16

2) Pythagorean theorem and reorganizing the formula so that the a value is found

Last week, the price of apples at a grocery store was $1.60 per pound. This week, apples at the same grocery store are on sale at a 10% discount. What is the total price of 4 1/2 pounds of apples this week at the grocery store?

Answers

Answer:

6.48 dollars total,

Step-by-step explanation:

First, you would want to multiply the amount of money per pound, by the amount of pounds. 1.60 multiplied by 4 1/2 or 4.5, would equal to 7.2 dollars. In order to find 10% of 7.2, your would need to multiply 7.2 by 0.10, which would give you 0.72. Then you would subtract 7.2 by 0.72 to get 6.48. So your answer would be 6.48 dollars.

Answer:

A=73

Step-by-step explanation:

sum of interior angles is (n-2)*180

5 sides, so (5-2)*180 = 3x180=540

sum of current interior angles (118+96+115+104)=433

subtract 540-433=107

construct the circumcenter

Answers

Answer: D) construct the circumcenter

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

Explanation:

Consider triangle ABC. The vertex points are at A,B,C. These represent the three cities in which the three different daughters live. Constructing the circumcenter will produce a circle such that all three points A,B,C are on that circle. Let's say that D is the center of that circle.

This means that AD, BD, CD are all radii of this same circle. Radii of the same circle are the same length, which is why point D is equally distant from A,B,C. If the mother lives at point D, then she will travel the same distance to visit any three of her daughters. See the note below.

To construct the circumcenter, we form perpendicular bisectors to segments AB, BC and AC. Technically you only need two of them. All three of these perpendicular bisectors intersect at point D.

Note: Keep in mind that roads aren't completely straight, so that means we'll have to factor in the curvature of each road. But to keep things simple, we assume each road is a straight line segment.

A ski slope is 320 yards long with a vertical drop of 100 yards. Find the

angle of elevation of the ski run. Round to the nearest degree.

Answers

Answer:

18°

Step-by-step explanation:

A ski slope is 320 yards long with a vertical drop of 100 yards. Find the

angle of elevation of the ski run. Round to the nearest degree.

The formula for angle of elevation is given as:

sin θ =Opposite/ Hypotenuse

Opposite = Vertical drop = 100 yards

Hypotenuse = Ski slope = 320 yards.

Angle of elevation =

sin θ = 100/320

sin θ = 0.3125

θ = arc sin(0.3125)

= 18.209956864°

Approximately = 18°

The number of yards that Janice used is calculated as:

1/3 yard + 1/6 yard

A projectile is thrown upward so that its distance above the ground after t seconds is h=-121t^2 +504t. After how many seconds does it reach it maximum height?

Answers

Answer:

2.08secs

Step-by-step explanation:

Given the equation modeled by the height as h=-121t^2 +504t

The velocity of the object at the max height is zero, hence;

v = dh/dt = 0

dh/dt = -2(121)t + 504

dh/dt = -242t + 504

0 = -242t + 504

242t = 504

t = 504/242

t = 2.08secs

Hence the projectile reaches its maximum height after 2.08secs

£330 is divided between Henry, Gavin & Jim so that Henry gets twice as much as Gavin, and Gavin gets three times as much as Jim. How much does Gavin get?

Answers

Answer: Gavin gets $99

Step-by-step explanation:

Step 1

LET amount  gotten by Jim be =x

amount  gotten by Gavin be = 3x

amount  gotten by Henry  be = 2  x 3x = 6x

Such that the total amount shared by the three of them can  be expressed as

x+ 3x + 6x = 330

Step 2

x+ 3x + 6x = 330

10x= 330

x= 330/10

x = 33

Jim gets $33

Gavin gets 3x= 3x 33= $99

Henry gets 6x= 6x 33= $198
