C. -9
D. 6

Answer:

Step-by-step explanation:

you have a right triangle, more precisely is a isosceles right triangle, as you have one angle= 45⁰, the other angle is also= 45⁰

In this triangle the hypotenuse, c, is

c=9[tex]\sqrt{2}[/tex]= 12.72

The area of the triangle ABC is 34.2 square centimeters

The complete question is in the image

Start by calculating the semi-perimeter using:

s = 0.5 * (a + b + c)

This gives

s = 0.5 * (9 + 10 + 8)

Evaluate

s = 13.5

The area is then calculated as:

[tex]A = \sqrt{s * (s - a) * (s - b) * (s - c)[/tex]

This gives

[tex]A = \sqrt{13.5 * (13.5 - 9) * (13.5 - 10) * (13.5 - 8)[/tex]

Evaluate

A = 34.2

Hence, the area of the triangle ABC is 34.2 square centimeters

Answer:

He must pay $129.45 and the total amount due is $3,629.45.

Step-by-step explanation:

I (interest) =P (principal) x R (rate) x T (time)

I=3500x.09x150/365

I=129.45

A (amount due) = P (principal) + I (interest)

A= 3500 + 129.45

A= $3629.45

Answer:

y = -3

Step-by-step explanation:

The given line is a horizontal line thru -5 on the y-axis.

Your line is parallel to y = -5, hence is also a horizontal line and passes thru (2, -3).  Since -3 is the y-coordinate of that point, y = -3 is the equation of the line you are looking for.

Step-by-step explanation:

kindly use English. i will hep

-3: y = -2 * (-3) - 7 = 6 - 7 = -1

0: y = -2 * 0 - 7 = -7

3: y = -2 * 3 - 7 = -6 - 7 = -13

6: y = -2 * 6 - 7 = -12 - 7 = =-19

Answer:

x = 22 degrees

Step-by-step explanation:

Since this is a right angle and both angles added together will equal to 90degrees this means that:

(3x-5) + (x+7) = 90

(first, remove the brackets)

3x-5+x+7 = 90

( add the numbers together and the term x together)

( 3x+x ) + ( -5+7 ) = 90

4x + 2 = 90

(subtract 2 from both sides)

4x = 88

(divide by 4 from both sides)

x = 22

so the measure of x = 22 degrees

Answer:

[tex]\frac{4}{3 - i} = \frac{6}{5} + \frac{2}{5}i[/tex]

Step-by-step explanation:

Given

[tex]\frac{4}{3 - i}[/tex]

See attachment for question

Required

Correct Ramon's error

Start by rationalizing the expression:

[tex]\frac{4}{3 - i} = \frac{4}{3 - i}*\frac{3 + i}{3 + i}[/tex]

[tex]\frac{4}{3 - i} = \frac{4(3 + i)}{(3 - i)(3 + i)}[/tex]

Expand

[tex]\frac{4}{3 - i} = \frac{12 + 4i}{3^2 - i^2}[/tex]

[tex]\frac{4}{3 - i} = \frac{12 + 4i}{9 - i^2}[/tex]

In complex numbers:

[tex]i^2 = -1[/tex]

So:

[tex]\frac{4}{3 - i} = \frac{12 + 4i}{9 - (-1)}[/tex]

[tex]\frac{4}{3 - i} = \frac{12 + 4i}{9 +1}[/tex]

[tex]\frac{4}{3 - i} = \frac{12 + 4i}{10}[/tex]

Split fraction

[tex]\frac{4}{3 - i} = \frac{12}{10} + \frac{4i}{10}[/tex]

[tex]\frac{4}{3 - i} = \frac{6}{5} + \frac{2}{5}i[/tex]

Answer:

(x + 5)^2 = (5 - 3)^2

Step-by-step explanation:

Given the equation;

x^2 + 10x + 22 = 13

We have;

x^2 + 10x = 13 - 22

x^2 + 10x = -9

Adding half of 10 to both sides and completing the square as usual, we have;

(x + 5)^2 = 5^2 + (-9)

(x + 5)^2 = (5 - 3)^2

Answer:

  x ≈ 24.91

Step-by-step explanation:

It is helpful to remember the mnemonic SOH CAH TOA. It is intended to remind you that ...

  Sin = Opposite/Hypotenuse

You observe that the values are given in the figure for an acute angle in a right triangle, the hypotenuse, and the side opposite the angle. That is why you are interested in the sine relation.

  sin(49°) = x/33

  x = 33·sin(49°) ≈ 24.905

The length of side x is about 24.91 units.

Answer:

  7.5 m

Step-by-step explanation:

The cosine relation applies.

  Cos = Adjacent/Hypotenuse

  cos(60°) = (distance to wall)/(15 m)

  distance to wall = (15 m)cos(60°) = (15 m)(1/2) = 7.5 m

The foot of the ladder is 7.5 m from the wall.

Answer:

1. I don't know how to solve that sorry :(

3. 30° = q

4. I don't know sorry :(

Step-by-step explanation:

1. I don't know how to solve that sorry :(

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

2. B. It is a diameter

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

3. All triangles = 180°

180° = 60° + 90° + q

180° = 150° + q

180° - 150° = 150° - 150° + q

30° = q

180° = 60° + 90° + 30°

180° = 150° + 30°

180° = 180°

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

4. I don't know sorry :(

Step-by-step explanation:

Given

x = 3
