Please help!! "Quadrilateral ABCD is inscribed in the circle below. Find the measure of all four angles."~!!!!!
expeople1 [14]
For a cyclic quadrilateral
The opposite angles are supplementary (meaning they sum up to 180 °)
I.e (x +20) ° + 3x ° =180 °
20 + 4x = 180
4x=180 - 20
4x = 160
Divide through by 4
x = 40 °

Angle at point A
(2x + 38) = (2(40) + 38) = 118 °

Angle at point B
3x = 3(40) = 120 °

Angle at point D
x + 20 = 40 + 20 = 60 °

Angle at point C
The total angle in a quadrilateral is 360 °
I.e 118 + 120 + 298 +

Please help me solve this. 4n – 19 = 29
Mrac [35]

Answer:

Solution of the equation is :  n=12

Step-by-step explanation:

Given equation:

4n - 19 = 29

Solving the equation for 'n'

Add '19' both sides:

4n-19+19=29+19

4n=29+19\\\\4n=48

Dividing by '4' both sides:

\frac{4n}{4}= \frac{48}{4} \\\\n=\frac{48}{4}\\\\ n=12

The Solution of the equation is :  n=12

Write the equation for a parabola whose vertex is (-6,-1) and passes through (-12,17).
Hitman42 [59]

Answer:

y=\frac{1}{2}(x+6)^2-1

Step-by-step explanation:

<u>Equation of the Quadratic Function</u>

The vertex form of the quadratic function has the following equation:

y=a(x-h)^2+k

Where (h, k) is the vertex of the parabola that graphically represents the function, and a is a coefficient different from zero.

The vertex of the required equation is located at (-6,-1)

The parabola passes through (-12,17)

Substituting the coordinates of the vertex, the equation of the function is:

y=a(x+6)^2-1

The value of a will be determined by using the given point:

17=a(-12+6)^2-1

Operating:

17=a(36)-1

36a=18\Rightarrow a=18/36=1/2

Solving:

a=1/2

The equation of the parabola is:

\boxed{y=\frac{1}{2}(x+6)^2-1}

Can anyone please teach me how to do this
alisha [4.7K]

Answer:

I will not give in answer but will give an example

Step-by-step explanation:

The area of irregular shapes can be determined by dividing the given shape into smaller regular shapes. The area of irregular shapes can be determined by dividing the given shape into smaller regular shapes.

In real life figures are often irregular shapes - a little bit messy. Think of your messy bedroom once more ‐ is it a perfect rectangle?

The trick is to break these figures into shapes that you know well and whose area you know how to find.

1. Find the area of this room:

3- 2 -4 -6 irregular shape

This can be done in two different ways but ill only give one example on how to find an area.

Method #1

Divide the figure into two rectangles and find all missing lengths.

The larger rectangle has an area of

4cm x 7cm = 28cm2

The smaller rectangle has an area of

4cm x 2cm = 8cm2

If we combine these we will find the total area:

28cm2 x 8cm2 = 36cm2

hope this helps :)
