Explain how you can use the triangle sum theorem to find the measures of the angles of an equilateral triangle

Rudiy27

The triangle Sum Theorem says that the sum of all the angles in a triangle has to equal 180 degrees. Since all three sides (and, consequently, angles) in an equilateral triangle are the same, you can divide 180 by 3 to find the measure of any angle of an equilateral triangle (60 degrees).

Mrs. Allan's car uses 8 gallons of gas for a 224-mile trip. Mrs. Owen's car uses 6 gallons of gas for a 210-mile trip. How many

Feliz [49]

Answer:

Mrs. Allan's Car will use 20 gallons of gas for 560 miles trip.

Mrs. Owen's Car will use 16 gallons of gas for 560 miles trip.

Step-by-step explanation:

Given:

Number of Miles for Mrs Allan car = 224 miles

Number of gallons of gas required = 8

We need to find the number of gallons of gas required for 560 miles for Mrs. Allan's car.

First we will find, in 1 gallons how many miles does Mrs Allan's Car drives.

For 8 gallons = 224 miles

So for 1 gallons = Number of miles in 1 gallon of gas

By using Unitary method we get;

Number of miles in 1 gallon of gas = $\frac{224}{8}= 28\ miles$

Now we know that;

for 28 miles = 1 gallon of gas is required.

So for 560 miles = Number of gallon of gas required in 560 miles.

Again by using Unitary method we get;

Number of gallon of gas required in 560 miles = $\frac{560}{28}= 20\ gallons$

Hence Mrs. Allan's Car will use 20 gallons of gas for 560 miles trip.

Also Given:

Number of Miles for Mrs Owen's car = 210 miles

Number of gallons of gas required = 6

We need to find the number of gallons of gas required for 560 miles for Mrs. Owen's car.

First we will find, in 1 gallons how many miles does Mrs Owen's Car drives.

For 6 gallons = 210 miles

So for 1 gallons = Number of miles in 1 gallon of gas

By using Unitary method we get;

Number of miles in 1 gallon of gas = $\frac{210}{6}= 35\ miles$

Now we know that;

for 35 miles = 1 gallon of gas is required.

So for 560 miles = Number of gallon of gas required in 560 miles.

Again by using Unitary method we get;

Number of gallon of gas required in 560 miles = $\frac{560}{35}= 16\ gallons$

Hence Mrs. Owen's Car will use 16 gallons of gas for 560 miles trip.

What is the solution set? −5x−6.5>12

Vesna [10]

-5x-6.5>12

Add 6.5 to both sides...

-5x>18.5

Divide both sides by -5 and flip the sign...

x<-3.7

Worth 48 points!!!! plz help me.

Mrac [35]

Answer:

see below

Step-by-step explanation:

1. The inverse means take the not of both sides

If it is Saturday, then there is no school.

Inverse If it is not Saturday, then there is school.

The converse flips the then and the if

If there is no school, then it is Saturday.

2.) The first given part is the if, what will happen is the then part

If you are a freshman, then you are required to attend orientation.

3.)

Given: 3x+1=-14 Prove: x=-5

Statements Reasons

1. 3x+1=-14 Given

2. 3x=-15 Subtraction Property of equality ( since we subtract 1 from each side)

3. X=-5 Division Property ( since we divide each side by 3)
