Need help with finding the value of x

Mathematics
2 answers:
Likurg_2 [28]3 years ago

Answer:

The value of x = 4.1 cm

Step-by-step explanation:

From the figure we can see a circle, with chord 15.6 cm

A right angled triangle with hypotenuse 8.8 cm

<u>To find the value of x</u>

By using Pythagorean theorem,

Base² + Height² = Hypotenuse²

Here Base  = x, Height = 15.6/2 = 7.8 cm and Hypotenuse = 8.8 cm

x² + 7.8² = 8.8²

x² = 8.8² - 7.8²

 = 77.4 - 60.84

 = 16.56

x = √16.56 = 4.07 ≈ 4.1 cm

Therefore the value of x = 4.1 cm

15.6/2 = 7.8
a^2 + b^2 = c^2
7.8^2 + x^2 = 8.8^2
60.84 + x^2 = 77.44
x^2 = 16.6
x = 4.1cm

Quadrilateral ABCD is a rectangle. If AG = -7j + 7 and DG = 5j + 43, find BD
Kaylis [27]

<em>BD</em> = 56

Step-by-step explanation:

Step 1: In rectangle, the diagonals are congruent and bisect each other.

So, <em>AC</em> = <em>BD</em>

⇒<em>AG</em> + <em>GC</em> = <em>BG</em> + <em>GD</em>

⇒<em>AG</em> + <em>AG</em> = <em>GD</em> + <em>GD</em>

⇒ 2<em>AG</em> = 2<em>GD</em>

⇒<em>AG</em> = <em>GD</em>

⇒ –7<em>j </em>+ 7 = 5<em>j</em> + 43

⇒–7<em>j</em> – 5<em>j</em> = 43 – 7

⇒–12<em>j</em> = 36

⇒<em>j</em> = –3

Step 2: <em>BD</em> = 2<em>DG</em>

<em>BD</em> = 2(5<em>j</em> + 43)

     = 2(5 (–3) + 43)

     = 2(–15 + 43)

     = 2 × 28

     = 56

Hence, <em>BD</em> = 56.

-3 1/2x - 4 = -38 1/8<br><br> How do I do this?
abruzzese [7]

Hello, I will try my best to explain this to you as simple as possible.

First, you have to pass the -4 to the other side, like this:

-3 1/2x - 4 = -38 1/8

              ↓

-3 1/2x = -38 1/8 - 4

Then, you have to subtract -4 from -38 1/8, like so:

-3 1/2x =  -38 1/8 - 4

              ↓

-3 1/2x = -42 1/8

My preferred method for this next step is this:

-3 1/2x = -42 1/8

              ↓

-7/2x = 337/8

Then, we divide:

-7/2x = -42 1/8

              ↓

x = (-337/8) / (-7/2)

x = 12.0357142857

So, the answer is: 12.0357142857.

Hope this helped! c:
