Given:

The figure of circle E. [tex]m\angle ABD=(11x-3)^\circ,m\angle ACD=(8x+15)^\circ[/tex].

To find:

The measure of arc AD.

Solution:

We know that the inscribed angles on the same arc are congruent and their measures are equal.

[tex]\angle ABD[/tex] and [tex]\angle ACD[/tex] are inscribed angles on the same arc AD. So,

[tex]m\angle ABD=m\angle ACD[/tex]

[tex]11x-3=8x+15[/tex]

[tex]11x-8x=3+15[/tex]

[tex]3x=18[/tex]

[tex]x=6[/tex]

Now,

[tex]m\angle ABD=(11x-3)^\circ[/tex]

[tex]m\angle ABD=(11(6)-3)^\circ[/tex]

[tex]m\angle ABD=(66-3)^\circ[/tex]

[tex]m\angle ABD=63^\circ[/tex]

We know that the intercepted arc is always twice of the inscribed angle.

[tex]m(Arc(AD))=2\times m\angle ABD[/tex]

[tex]m(Arc(AD))=2\times 63^\circ[/tex]

[tex]m(Arc(AD))=126^\circ[/tex]

Therefore, the measure of arc AD is 126 degrees.

Answer:

[tex]0.28\ \text{m}^2[/tex]

Step-by-step explanation:

[tex]4\ \text{cm}=0.2\ \text{m}[/tex]

[tex]1\ \text{cm}=\dfrac{0.2}{4}=0.05\ \text{m}[/tex]

[tex]28\ \text{cm}=28\times 0.05=1.4\ \text{m}[/tex]

The height of the layer is 0.2 m and the length is 1.4 m

Area is given by

[tex]0.2\times 1.4=0.28\ \text{m}^2[/tex]

Area of the actual quartz layer section is [tex]0.28\ \text{m}^2[/tex].

Answer:

C

Step-by-step explanation:

Given

x² - 2x + 2 = 0 ( subtract 2 from both sides )

x² - 2x = - 2

To solve use the method of completing the square

add ( half the coefficient of the x- term)² to both sides

x² + 2(- 1)x + 1 = - 2 + 1

(x - 1)² = - 1 ( take the square root of both sides )

x - 1 = ± [tex]\sqrt{-1}[/tex] = ± i ( add 1 to both sides )

x = 1 ± i , then

x = 1 + i or x = 1 - i → C

answer 2.5 i have solved the problem three times in my geometry class and got the same answer all three times

Considering the diagram below the value which represent the missing side, round to the nearest below, tenth, is 2 units.

Pythagoras theorem says that in a right angle triangle, the square of the hypotenuse side is equal to the sum of the square of the other two legs of right angle triangle.

The image of the given problem is attached below. In this diagram, the radius of the circle is 1.5 meter long.

The triangle ABC shown in the graph is right angle triangle as, the tangent of the circle is perpendicular with the radius of it at the point of contact.

Thus, by the Pythagoras theorem,

[tex](AB)^2+(BC)^2=(AC)^2\\(1.5)^2+(x)^2=(1.5+1)^2\\(x)^2=(2.5)^2-(1.5)^2\\x=\sqrt{6.25-2.25}\\x=\sqrt{4}\\x=2\rm\; units[/tex]

Thus, considering the diagram below the value which represent the missing side, round to the nearest below, tenth, is 2 units.

Answer:

I couldn't find the area, but the perimeter is 200.

Step-by-step explanation:

To get the answer of 200 perimeter, all you have to do is add up all the sides of the shape.

10+10+25+25+25+15+15+75 = 200.

After adding up the numbers, you are left with a perimeter of 200.

Respuesta:

No pude encontrar el área, pero el perímetro es 200.

Explicación paso a paso:

Para obtener la respuesta de 200 de perímetro, todo lo que tienes que hacer es sumar todos los lados de la forma.

10 + 10 + 25 + 25 + 25 + 15 + 15 + 75 = 200.

Después de sumar los números, te queda un perímetro de 200.

Answer:

(m + 2)

Step-by-step explanation:

First, factorise out m from the first equation:

m² + 2m = m (m + 2)

Second, use difference of two squares to factorise the 2nd equation:

m² - 4 = (m + 2) (m - 2)

Third, just factorise the last one normally as you would to solve for m:

m² + 3m + 2 = (m + 2) (m + 1)

Finally, to find the lowest common multiple, you need to identify what value goes into all of the equations and that is (m + 2).

Answer:

80%
