GEW has angle measures given by m/_G=5x + 66, m?/_ E = 3x, and m/_ W= 142 -4x whats the mesure of e

Answers

Answer:

21°

Step-by-step explanation:

GEW has angle measures given by m/_G=5x + 66, m?/_ E = 3x, and m/_ W= 142 -4x whats the mesure of e

= 5x + 66 + 3x + 142 - 4x = 180

4x + 208 = 180

4x = 208 - 180

4x = 28

x = 28/4

x = 7

Solving for E = 3x

E = 3 × 7

E = 21°

The distance on a map is 4.5 cm. The scale of the map is 1 : 1000. What is the actual distance?. Single choice.

Answers

Answer:

Actual distance is 4500 cm (45 m).

Step-by-step explanation:

A scale is a representative fraction that can be used to either increase or decrease proportionally the dimension of a given object.

scale = [tex]\frac{distance on map}{actual distance}[/tex]

It is in the form of a ratio.

From the question, Distance on map = 4.5 cm,

scale = 1 : 1000

        = [tex]\frac{1}{1000}[/tex]

scale = [tex]\frac{distance on map}{actual distance}[/tex]

Let the actual distance be represented by d.

So that,

[tex]\frac{1}{1000}[/tex] = [tex]\frac{4.5}{d}[/tex]

⇒  d = 4.5 x 1000

       = 4500

    d = 4500

The actual distance is 4500 cm (45 m).

50 pts and brainliest. Is the ratio of arc length to r always equal to pi? What is it equal to?

Please only answer if you know it, this is super important!! If it's right I'll mark you brainliest!

Answers

Answer:

It can sometimes be equal to π. However, it is equal to our central angle.

Step-by-step explanation:

First, recall that arc length is given by:

[tex]s=r\theta[/tex]

Where s is the arc length, r is the radius, and θ is the central angle of the arc in radians.

So, the ratio of the arc length to the radius is:

[tex]\displaystyle \frac{r\theta}{r}[/tex]

The radius r cancels. Hence, we are left with:

[tex]=\theta[/tex]

So, the ratio of the arc length to the radius does not equal π (although it can sometimes if the central angle is π radians (or 180°)). Rather, the ratio is equivalent to the central angle.

So, for example, if we have a circle with radius 7 with a central angle of 3π/2 (this gives us an arc length of 21π/2), then the ratio of the arc length to the radius will be 3π/2 (our central angle).

Answer:

Sometimes it can be equal to π. It is equal to our central angle.

Step-by-step explanation:

Recalling arc length is given by:

Where s is the arc length, r is the radius, and θ is the central angle of the arc in radians.

So, the ratio of the arc length to the radius is:

rθ/θ

The radius r cancels. Hence, we are left with:
