If A = 30° and r = 12, find x. (Round your answer to the nearest whole number.)

If A = 30 And R = 12, Find X. (Round Your Answer To The Nearest Whole Number.)

Answers

Answer 1

Answer:

[tex]\boxed{12}[/tex]

Step-by-step explanation:

A = 30° and r = 12

[tex]\sin A = \frac{r}{r + x}[/tex]

[tex]\sin 30 = \frac{12}{12 + x}[/tex]

[tex]\frac{1}{2} = \frac{12}{12 + x}[/tex]

[tex]1(12 + x) = 2(12)[/tex]

[tex]12 + x = 24[/tex]

[tex]x = 24 - 12[/tex]

[tex]x = 12[/tex]

AAS

Step-by-step explanation:

AAS stands for Angle-Angle-Side. Here, you are given two angles and one side that is not included in the angles that are corresponding to the angles and side of another triangle, so they are congruent by the AAS rule.

You may be asking why the ASA (angle-side-angle) is not applicable. This is because the side in the ASA rule should be between the two angles, in this case, the 10-unit-side is not in between the two angles but rather nearer to the angle 70°, so ASA is not the right answer.

Please answer ASAP will mark brainliest!! XŻ bisects The measurement of of X?

Answers

Answer:

x = 57

Step-by-step explanation:

XZ divides <WXY into two equal parts. Which implies that:

m<ZXY = m<ZXW

Therefore:

m<WXY = 2(m<ZXY)

m<ZXY = 58°

m<WXY = 2x + 2

Plug in the values into the equation

2x + 2 = 2(58)

2x + 2 = 116

2x = 116 - 2 (subtraction property of equality)

2x = 114

x = 114/2 (division property of equality)

x = 57

Give an example of a quadratic function that has two real solutions with a multiplicity of 2.

Answers

Answer:

The equation is;

x^2 + 4x + 4 = 0

Step-by-step explanation:

Here, we want to give a quadratic equation with a real solution that has a multiplicity of two

Generally, there are only two solutions to a quadratic equation since it is a polynomial of degree two

Since we have a multiplicity of 2, it means that the real roots are repeated

Let us have a solution of x = -2

With the multiplicity;

we have x + 2

So let us expand this

(x+2)(x+2)

= x^2 + 4x + 4

The equation is;

x^2 + 4x + 4 = 0

Determine of which lines, if any, are parallel or perpendicular. Explain.
Line a passes through (-2, 1) and (0,3).
Line b passes through (4,1) and (6,4).
Line c passes through (1,3) and (4,1).

Answers

Answer:

lines b and c are perpendicular

Step-by-step explanation:

Use slope

slope for parallel is the same

slope for perpendicular is negative reciprocal

line a slope- 1-3/-2-0 is -2/-2 or 1

line b slope- 1-4/4-6 is -3/-2 or 3/2

line c slope- 3-1/1-4 is 2/-3 or - 2/3

none are the same so none are parallel

- 2/3 is the negative reciprocal of 3/2 so lines b and c are perpendicular

Solve the following system of equations by the substitution method. 2x = 10y - 8 3x + 4y + 5 = 0

Answers

Answer:

x = [tex]-\frac{41}{19}[/tex]

y = [tex]\frac{7}{19}[/tex]

Step-by-step explanation:

2x = 10y - 8

3x + 4y + 5 = 0

2x = 10y - 8

x = 5y - 4

3x + 4y + 5 = 0

3 ( 5y - 4 ) + 4y + 5 = 0

19y - 7 = 0

19y = 7

y = [tex]\frac{7}{19}[/tex]

x = 5y - 4

x = 5 ( [tex]\frac{7}{19}[/tex] ) - 4

x = [tex]-\frac{41}{19}[/tex]

-12(a-2)=-50 help help help

Answers

Answer:

a = 37/6

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to Right

Equality Properties

Step-by-step explanation:

Step 1: Define equation

-12(a - 2) = -50

Step 2: Solve for a

Divide -12 on both sides:                    a - 2 = 25/6Add 2 on both sides:                          a = 37/6

Step 3: Check

Plug in a into the original equation to verify it's a solution.

Substitute in a:                    -12(37/6 - 2) = -50Subtract:                              -12(25/6) = -50Multiply:                               -50 = -50

Here we see that -50 does indeed equal -50.

∴ a = 37/6 is a solution of the equation.

Answer:

a = [tex]\frac{37}{6}[/tex]

Step-by-step explanation:

-12(a - 2) = -50

-12a + 24 = -50

-12a = -74

a = [tex]\frac{74}{12}[/tex] = [tex]\frac{37}{6}[/tex]
