Calculate the measure of angle ADB if angle ACB is 50 degrees.

Answers

Answer:

ADB=50°

Step-by-step explanation:

Angles subtended by the same segment are equal

Therefore,the angle ∠[tex]ADB=40[/tex] degree.

What are the angles?

An angle is a form of geometrical shape, that is constructed by joining two rays to each other at their end-points.

Here given that ∠[tex]ACB=50[/tex] degree and we know alternates angles are equal so ∠[tex]CAD=50[/tex] degree.

And [tex]AD[/tex] is parallel to [tex]BC[/tex].

Therefore, the diagonals of a rhombus are at right angled.

So, ∠[tex]AOD=90[/tex] degree

Now, In Δ[tex]AOD[/tex],

∠[tex]ADO+[/tex]∠[tex]DAO+[/tex]∠[tex]AOD=180[/tex] degree

∠[tex]ADO+50+90=180[/tex]

∠[tex]ADO=+140=180[/tex]

∠[tex]ADO=180-140[/tex]

∠[tex]ADO=40[/tex] degree

∠[tex]ADB=40[/tex] degree.

Hence, the angle ∠[tex]ADB=40[/tex] degree.

The height, h, in feet of a piece of cloth tied to a waterwheel in relation to sea level as a function of time, t, in seconds can be modeled by the equation h = 15 cosine (StartFraction pi Over 20 EndFraction t). How long does it take for the waterwheel to complete one turn? 5 seconds 10 seconds 20 seconds 40 seconds.

Answers

Solving the trigonometric equation, it is found that it takes 40 seconds to complete one turn.

The height is modeled by:

[tex]h(t) = 15\cos{\left(\frac{\pi}{20}t\right)}[/tex]

The initial height is [tex]h(0) = 15[/tex], hence, one turn is completed when h(t) = 15.

[tex]h(t) = 15\cos{\left(\frac{\pi}{20}t\right)}[/tex]

[tex]15 = 15\cos{\left(\frac{\pi}{20}t\right)}[/tex]

[tex]\cos{\left(\frac{\pi}{20}t\right)} = \frac{15}{15}[/tex]

[tex]\cos{\left(\frac{\pi}{20}t\right)} = 1[/tex]

The length of one turn is of [tex]2\pi[/tex], and [tex]\cos{(2\pi)} = 1[/tex], hence, the solution is found according to:

[tex]\frac{\pi}{20}t = 2\pi[/tex]

[tex]t = \frac{40\pi}{\pi}[/tex]

[tex]t = 40[/tex]

It takes 40 seconds to complete one turn.

A polygon with area 10 square units is dilated by a scale factor of k. Find the area of the image for each value of k.
a k=4
square units
b. k=1.5
square units
ck=1
square units

Answers

Answer:

a = 160 square units

Step-by-step explanation:

The areas of the image are 160, 22.5 and 10 square units

The area of the polygon is given as:

A =10 square unit

The area of the image of the polygon is calculated as:

[tex]A_k = A * k^2[/tex]

When k = 4, we have:

[tex]A_4 = 10 * 4^2[/tex]

[tex]A_4 = 160[/tex]

When k = 1.5, we have:

[tex]A_{1.5} = 10 * 1.5^2[/tex]

[tex]A_{1.5} = 22.5[/tex]

When k = 1, we have:

[tex]A_{1} = 10 * 1^2[/tex]

[tex]A_{1} =10[/tex]

Hence, the areas of the image are 160, 22.5 and 10 square units

It was for the welfare of the Armenian societiesD. The Armenians had committed crimes against the state.Reading excerpt that goes with the questionAt the beginning of the 20th century, there were between 2 and 2.5 million Armenians living in the Ottoman Empire, and millions of Armenians also lived beyond the eastern border of the Ottoman Empire, in territory held by Russia. The Turks Anti-Armenian feelings in the Ottoman Empire erupted into mass violence several times in the late 19th and early 20th centuries When the nationalistic Young Turks party came to power in 1908, violence against Armenians became much more common. Because the main goal of the nationalistic Turkish government was to Turkify the empire (to make all the people in the empire follow Turkish culture), policies became less tolerant of non-Turks and Christians over time. In October 1914, the Ottoman Empire entered World War I on the side of Germany and attacked Russia. Since the vilayets where many Armenians lived were near the Russian-Ottoman border, which was now a war front, the Ottoman government and many Turks accused the Armenians of siding with the Russians. The Young Turks began a propaganda campaign portraying Armenians as an internal enemy.Our fellow countrymen, the Armenians, who form one of the racial elements of the Ottoman Empire, having taken up, as a result of foreign instigation for many years past, with a lot of false ideas of a nature to disturb the public order, and because of the fact that they have brought about bloody happenings and have attempted to destroy the peace and security of the Ottoman state, of their fellow countrymen, as well as their own safety and interests, and, moreover, as the Armenian societies have now dared to join themselves to the enemy of their existence, our Government is compelled to adopt extraordinary measures and sacrifices, both for the preservation of the order and security of the country and for the continuation of their existence and for the welfare of the Armenian societies. Therefore, as a measure to be applied until the conclusion of the war, the Armenians have to be sent away to places which have been prepared in the interior vilayets1 What does the simile mean between a roller coaster can feel like flying Solve 3(x13)=y2 for y.
