**CHALLENGE** Find All Of The Missing Angles - A, B, C, And D.

Answers

Answer 1

Answer:

a = 65°

d = 75°

b  = 25°

c = 25°

Explanation:

To solve the given problem, we are going to use different angle theorems.

Using these theorems, it would be possible to establish the relationship between the unknown and given angles.

A.

To solve for angle a, we are going to use the concept of angles on a straight line.

    The sum of angles on a straight line is 180°

 Therefore;

             60 + 55 + a  = 180

                   115 + a  = 180

                            a = 180 - 115

                            a = 65°

B. To solve for angle d, we are going to use the concept of right angles.

   Angle in a right angle is 90°;

            So:

                  d + 15 = 90

                   d = 90-15 = 75°

C. To find angle, b, since we know a, we use angles in a right angle triangle.

   Sum of angles in triangle  = 180°

       a + b + 90 = 180

            b = 180 - 90 -a

            b = 90 - 65 = 25°

D. Angles b and c are vertically opposite and can be said to be the same.

  So b = c

             c  =  25°

What is Seismometer?

A seismometer is a device that detects vibrations in the ground brought on by explosions, volcanic eruptions, and earthquakes. A seismograph is typically made up of them along with a timing device and a recording device.

A seismograph, also known as a seismometer, is a device used to identify and document earthquakes. It typically consists of a mass that is fastened to a fixed base. The base moves during an earthquake but the mass does not. It is common to convert the base's motion with respect to the mass into an electrical voltage.

Commonwealths _______________________ .
A. only have ceremonial ties to their mother country
B. are involuntarily linked to a mother country
C. are not dependent upon their mother countries after gaining independence
D. are dependent upon their mother countries for defense and foreign policy issues

Answers

Answer:

Commonwealths are dependent upon their mother countries for defense and foreign policy issues.

Explanation:

A is not correct because the commonwealths have complex relations with their mother country, and even though they are governing themselves, they still are heavily dependent on certain things from their mother country.

B is not correct because these territories are voluntarily linked to the mother country, and the main reason is that they are still in some part dependent on it.

C is not correct because the majority of these territories are dependent on their mother countries, some for defense, some financially, some for disputes...

D is correct because pretty much all of these territories are dependent on defense and foreign policy issues on their mother countries, despite often being able to sustain themselves economically and socially.

Sam is rowing a boat away from a dock. the graph shows the relationship between time and Sam's distance from the dock. evaluate the function for an input of 3.


A. after 3 minutes, Sam is 3 meter from the dock.


B. after 40 minutes, Sam is 40 meters from the dock.


C. after 40 minutes, Sam is 3 meters from the dock.


D. after 3 minutes, Sam is 40 meters from the dock.

Answers

Answer:

D. after 3 minutes, Sam is 40 meters from the dock.

Explanation:

For an input of 3, the function will produce a value of 40. That is in 3 minutes, the boat would have covered a distance of 40meters.

We can solve this problem using the given graph.

We know that this is a distance - time graph. The slope of this graph gives the value of the speed of the boat.

From the time - axis, mark point 3 which corresponds to the input given. Trace it up to the point where it coincides with the graph. Then find the distance axis value of the point. Doing this yield 40m

So, in 3 minutes, Sam will row a distance of 40m.
