Answer:
100 degrees

Triangles add up to 180 degrees

30 + 50 = 80

180 - 80 = 100

Triangles add up to 180 degrees

30 + 50 = 80

180 - 80 = 100

Answer:

When you indicate triangle congruency, the order of the letters matter. As you see these statements, look at how the side length names correspond to how the letters are written in its order, ΔABC ≅ ΔDEF. (By the way, triangles aren't equal with an = sign. It's a ≅ congruency sign.)

AB is congruent or the same length as DE.

BC is congruent or the same length as EF.

AC is congruent or the same length as DF.

In the same way, all of the angles in the corresponding order are ALSO congruent. By the way, we say that angles are **congruent** and angle MEASURES (like 30 degrees) are **equal**.

m∠A = m∠D

m∠B = m∠E

m∠C = m∠F

In the same way, we can try to find m∠C, or measure C!

1. Let's find the missing angle!

So, we know that m∠A is 50 degrees and m∠E is 30 degrees. Since we know that m∠E = m∠B because of the order of the triangles, now we know two of the angles in triangle ABC.

m∠A = 50 degrees

m∠B = 30 degrees

m∠C = 180 degrees - (50 + 30) = 100 degrees

(We minus from 180 degrees because 180 degrees is the sum of the angles in a triangle!)

And that's it! If you have any questions, please feel free to ask questions. I'm not here to judge, and I'm only here to help. Again, ask questions if you need help. It's crucial that you know the basics of geometry!

**Answer:**

7

**Step-by-step explanation:**

You must divide 28 by 4 which equals 7.

The **acceleration** of the object is 400 m/s²

To find the **acceleration **of an object when a 40 N force is applied to it with a mass of 0.1 kg on a **frictionless surface**, we can use Newton's second law of motion, which states that the acceleration of an object is **directly proportional** to the net force acting on it and inversely proportional to its mass.

The formula for **Newton's second law** of motion is:

F = ma

where:

F is the **net force**,

m is the **mass** of the object,

a is the acceleration.

In this case, the net force is 40 N and the mass of the object is 0.1 kg.

Substituting these values into the formula, we get:

40 N = (0.1 kg) a

Solving for a, we get:

a = 400 m/s²

Therefore, the acceleration of the object is 400 m/s²

**Answer:**

The equation in point-slope is .

**Step-by-step explanation:**

**Point-slope** is a specific form of linear equations in two variables:

When an equation is written in this form, m gives the slope of the line and (a, b) is a point the line passes through.

We want to find the equation of the line that passes through (4, 7) and whose slope is -2. Well, we simply plug m = -2, a = 4, and b = 7 into point-slope form.

Don has the **longest **section of pipe because the **fraction **number 11/16 is **greater **than the **fraction **number 2/3.

Algebra is the study of **abstract **symbols, while **logic **is the manipulation of all those **ideas**.

The **decimal **number is the sum of a **whole **number and part of a fraction number. The **fraction **number is greater than zero but **less **than one.

David says he has 2/3 of a line **length **left, while Wear says he **has **11/16 of a **length **left.

Convert the **fraction **numbers 2/3 and 11/16 into the **decimal **number. Then we have

2/3 = 0.6667

11/16 = 0.6875

The **decimal **number 0.6875 is greater than 0.6667. Then the **fraction **number 11/16 is **greater **than the **fraction **number 2/3.

Don has the **longest **section of pipe because the **fraction **number 11/16 is **greater **than the **fraction **number 2/3.

#SPJ2

**Answer:**

Don

**Step-by-step explanation:**

1. We make the fractions have common denominators so it is easier to compare them. We can do this buy multiplying 2/3 by a factor of 16, so it becomes 32/48. For 11/16, we multiply by a factor of 3 so it becomes 33/48. It is now apparent that Don has the longer pipe.

**Answer:**

UV = 15

BD= 31

**Step-by-step explanation:**

Since, U is the midpoint of TV.

Therefore,

TU = UV

x + 10 = 3x

x - 3x = - 10

-2x = - 10

x = - 10/-2

x = 5

UV = 3x = 3*5

UV = 15

BD = BC + CD

3x - 11 = x - 2 + 19

3x - 11 = x + 17

3x - x = 11 + 17

2x = 28

x = 28/2

x = 14

BD = 3x - 11 = 3*14-11 = 42 - 11

BD= 31

We used the relationship that BC + CD = BD and then solved for x, which we found to be 14. We then substituted 14 for x in the equation for BD, which gave us a result of 31.

In the given question, we have a piece of a line divided into different sections: BC, BD, and CD with their respective lengths. BD is represented through a variable equation. We know that BC + CD = BD, this is a fundamental property of geometry that the sum of the lengths of two consecutive sections of a line is equal to the total length. So, substitute the given values:

**x − 2 + 19 = 3x − 11**

Simplify the equation by combining like terms: ** x + 17 = 3x - 11**. Now, let's solve for x:

First, consolidate x's on one side by subtracting 'x' on both sides. We get **17 = 2x - 11**.

Next, add 11 on both sides to solve for x. We get, **28 = 2x**.

Finally, divide by 2 on both sides to find x, **x = 14**.

Now, we can find BD by substituting x into the equation 3x - 11, we get:

**BD = 3*14 - 11 = 42 - 11 = 31**.
