You can use the ASA postulate which means angle side angle. if 2 angles and the including side are congruent to the corresponding parts of another triangle then the triangles are congruent. hope that helps :)

Answer:

Following Theorems and postulates used to prove two triangles are congruent:

1). Side-Side-Side ( SSS ) congruence rule,

When three sides of one triangle are equal to three sides of another triangle , then the two triangles are congruent

2). Side-Angle-Side ( SAS ) congruence rule,

When two sides of one triangle are equal to two sides of another triangle and the an angle between two sides of one triangle equal to angle between two sides of another triangle , then the two triangles are congruent

3). Angle-Side-Angle ( ASA ) Congruence Rule,

When two angles of one triangle are equal to two angles of another triangle and side between two angles of one triangle equal to side between two angles of another triangle, then the two triangles are congruent.

4). Right angle - Hypotenuse - side ( RHS ) Congruence Rule,

If in two right triangles the hypotenuse and one side of on triangle are equal tot he hypotenuse and one side of other triangle, then the triangles are congruent.

Note:

there is also Angle-Angle-Side ( AAS ) Congruence Rule,

When two angles of one triangle are equal to two angles of another triangle and any side of one triangle equal to any side of another triangle, then the two triangles are congruent.

Which would the phrase "two times the quotient of a number and 3" look like as a variable expression?
Naya [18.7K]
2 n/3 would be the closest answer although it looks as if the 2 is supposed to be multiplied by n/3 which would lead me to write it as 2(n/3)

7 divided by somethings equal 7.35
Dmitriy789 [7]
Let's translate it into an equation and then solve...

7/x = 7.35
x * 7/x = 7.35 * x
7 = 7.35x
7/7.35 = x
 .9524 = x

So 7 divided by .9524 (rounded to the nearest ten thousandth) equals 7.35

Question 14. A carousel makes one complete revolution every 75 seconds. Levi sits on the carousel 4 feet from its center. If the
garik1379 [7]

Answer:

The correct option is;

H. 32·π

Step-by-step explanation:

The given information are;

The time duration for one complete revolution = 75 seconds

The distance from the center of the carousel where Levi sits = 4 feet

The time length of a carousel ride = 5 minutes

Therefore, the number of complete revolutions, n, in a carousel ride of 5 minutes is given by n = (The time length of a carousel ride)/(The time duration for one complete revolution)

n = (5 minutes)/(75 seconds) = (5×60 seconds/minute)/(75 seconds)

n = (300 s)/(75 s) = 4  

The number of complete revolutions - 4

The distance of 4 complete turns from where Levi seats = 4 ×circumference of circle of Levi's motion

∴ The distance of 4 complete turns from where Levi seats = 4 × 2 × π × 4 = 32·π.

Write an equation parallel to y=3x+6 that passes through the point (4, 7)
HACTEHA [7]

Answer:

y = 3x - 5

Step-by-step explanation:

The equation of a line parallel to y=3x+6 has exactly the same form but a different constant on the right:  y=3x+C

To find C, take the coordinates of the given point and substitute them into y=3x+C:

7 = 3(4) + C, or

7 = 12 + C, and so C = -5

The desired equation is y = 3x - 5
