### Answers

**Answer:**

65º

**Step-by-step explanation:**

(the sum of the angles of a triangle) 180- 65= 115

65= 30+ 35

180- 115=65

**Answer:**

I'm pretty sure the answer is 65

**Step-by-step explanation:**

30+35=65

180-65=115

So the 3rd angle in the triangle is 115°

Then you subtract 115 from 180 and get 65°

So S equals 65°

### Answers

**Answer:**

**y - 13 = -2(x+7)**

**Step-by-step explanation:**

**Given**

Coordinate point (-7, 13)

Slope m = -2

We can express the euation of the line in point slope form as shown;

The point slope form of the equation is expressed as;

y - y0 = m(x-x0)

x0 = -7, y0 = 13 and m = -2

Substitute;

y - 13 = -2(x-(-7))

**y - 13 = -2(x+7)**

**Hence the required equation in point- slope form is y - 13 = -2(x+7)**

### Answers

**Answer:**

the answer is -8

**Step-by-step explanation:**

Well, first you have to make an equation for what x equals, if that makes sense. So you take the x-y=6 and add y on both sides to get x=(y+6). Then you plug that.

Brianna has a container with a volume of 1.5 L she estimates the volume to be 2.1 m what is the percent error

### Answers

**Answer: 40%**

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

Work Shown:

Subtract the values to get 2.1-1.5 = 0.6

Brianna is off by 0.6 liters

Divide that error by the true value 1.5 to get 0.6/1.5 = 0.40

Then move the decimal point 2 spots to the right to arrive at **40%**

Therefore, **the percent error is 40%**

------------------

The formula you can apply is:

[tex]P = \frac{|G-T|}{T}*100\%[/tex]

where

P = percent error

G = guess value (in this case it is 2.1)

T = true value (which is 1.5 in this case)

If we were to apply the formula, then we get:

[tex]P = \frac{|G-T|}{T}*100\%\\\\P = \frac{|2.1-1.5|}{1.5}*100\%\\\\P = \frac{|0.6|}{1.5}*100\%\\\\P = \frac{0.6}{1.5}*100\%\\\\P = 0.40*100\%\\\\P = 40\%\\\\[/tex]

Figure ABCD has vertices A(- 5, 2) , B(4, 2) , C(4, - 5) , and D(- 5, - 3) . What is the area of Figure ABCD? 9 square units 45 square units 54 square units 122 square units

### Answers

**Answer:**

54 square units

**Step-by-step explanation:**

ABCD = ABED + CED

A and B have same y coordinate

A and D have same x coordinate

AB ⊥ AD

AB = 4 - (-5) = 9

AD = 2 - (-3) = 5

EC = BC - AD = (2 + 5) - 5 = 2

ABCD = 9 x 5 + 1/2 (9 x 2) = 45 + 9 = 54

Why is the ? in the proportion below equal to QR? Explain why.

A) SQ is the geometric mean between the hypotenuse and the closest adjacent segment of the hypotenuse.

B) SQ is the shortest leg and so is the geometric mean between the entire leg and the hypotenuse.

C) SQ is the hypotenuse and is opposite the angle S in the right triangle QSR.

D) SQ is the hypotenuse and thus the Hypotenuse Rule of Geometric Means applies.

### Answers

9514 1404 393

**Answer:**

A) SQ is the geometric mean between the hypotenuse and the closest adjacent segment of the hypotenuse.

**Step-by-step explanation:**

In this geometry, all of the right triangles are similar. That means corresponding sides have the same ratio (are proportional).

Here, SQ is the hypotenuse of ΔSQT and the short side of ΔRQS.

Those two triangles are similar, so we can write ...

(short side)/(hypotenuse) = QT/SQ = QS/RQ

In the above proportion, we have used the vertices in the same order they appear in the similarity statement (ΔSQT ~ ΔRQS). Of course, the names can have the vertices reversed:

QT/SQ = SQ/QR . . . . . QS = SQ, RQ = QR

__

When this is rewritten to solve for SQ, we get ...

SQ² = QR·QT

SQ = √(QR·QT) . . . . **SQ (short side) is the geometric mean of the hypotenuse and the short segment**.

The base of a cone shaped glass is 12 inches and it is 18 inches tall. You

fill the glass with soda pop to the top of the glass. What is the volume of

soda pop

### Answers

**Answer:**

**Step-by-step expla**

To find the volume of a cone, use the equation: V = 1/3Bh.

In this equation, V is the volume, B is the base, and h is the height.

We are given that the base is 12 inches, and the height is 18 inches. With those necessary values, we can substitute those values, and calculate it.

V = 1/3(12)(18)

V = 4(18)

V = 72.0

Therefore, the volume of this glass is 72.0 cubic inches.

Which of the following is an open statement?

A) An angle that measures 40° is an acute angle.

B) An angle that measures 95° is an obtuse angle.

C)

XYZ is an acute angle.

OD) An angle that measures 95° is an acute angle

### Answers

**Answer:**

OD

**Step-by-step explanation:**

an angle that is more than 90 is considered a acute angles

The correct option for an **open statement** is:

C) XYZ is an acute angle.

The answer is C. We don't know if it's true or false.

Here, we have,

we know that,

An open statement is one that can be true or false depending on the value or condition being discussed.

In this case, the statement "An **angle **that measures 95° is an acute angle" is an open statement because it can be evaluated as true or false based on the definition of an **acute angle**.

An **acute angle** is defined as an angle that measures less than 90 degrees.

Since 95° is greater than 90°, the statement is false.

However, if we were discussing a** different angle** measure, the statement could be true or false depending on its value.

Options A and B are not open statements because they provide specific angle measures (40° and 95°) and classify them as either acute or obtuse, which can be determined as true or false based on their given measures.

Option C does not provide **any specific **information or condition,

We don't know if it's true or false.

The correct option for an **open statement** is:

C) XYZ is an acute angle.
