Answers

Answer 1

Answer:

Given:

There are 4 statements and we need to find the answer of each statement.

Statement 1:

m ∠ABC + m ∠BAC + m ∠ACB when Δ ABC is an isosceles triangle

Sum of all interior angles of a triangle is always equal to 180°.

⇒  m ∠ABC + m ∠BAC + m ∠ACB = 180°

Therefore, the correct option is (B).

Statement 2:

m∠ABC when m∠BAC = 70° and ΔABC is an isosceles triangle

From the triangle ABC, ∠A = 70, ∠B = ∠C(Isosceles triangle property)

Let ∠B = ∠C = 'x'.

Sum of all interior angles of a triangle is always equal to 180°.

⇒  m ∠ABC + m ∠BAC + m ∠ACB = 180°

m ∠ABC = ∠B = 55° [Option (A)]

Statement 3:

m∠QPR when m∠QRP = 30° and ΔPQR is an isosceles triangle.

From the triangle QPR, ∠R = 30°, QP ≅ QR

Now, from isosceles triangle definition, the angles opposite to the congruent sides are also congruent. Therefore,

∠P = ∠R = 30°

Now, m∠QPR is same as ∠P. So,  m∠QPR = 30° [Option D].

Statement 4:

m∠BDE when m∠BAC = 45° and points D and E are the midpoints of AB and BC, respectively, in ΔABC

From the figure shown below,

DE is the midsegment of sides AB and BC. Therefore, from midsegment theorem, DE || AC (third side).

Therefore, for two parallel line DE and AC cut by transversal AB,

m∠BDE = m∠BAC (Corresponding angles are congruent)

m∠BDE = 45°

Why are dams important? Give at least two reasons and explanations

Answers

Explanation:

A dam is an artificial barrier that controls the flow of water.

Dams are very useful for the following reasons:

They are sources of hydro-electric power production: most dams in the world are used to generate this environmentally friendly source of power. The water in the dam is used to drive heavy turbines which in turn produces electric current. They are sources of water for irrigation: during the dry season when water is scanty, water in the dam can be channeled for farming and other agricultural purposes. A potential source of tourism: they are used in generating revenue as result of their touristic outlay.

3(b). Muscular endurance is defined as:​

Answers

3(a) The correct answer is D: All of the above.

3(b) Muscular endurance is the ability of a muscle or group of muscles to perform repetitive contractions against a force for an extended period of time. The greater your muscular endurance the higher number of repetitions you could complete.

Exercise is often described as training and should include All of the above.

Thus, option D is correct.

What is Muscular endurance?

The capacity of a muscle a particular muscle grouping to sustain repeated spasms against such a force over a protracted period of time is referred to as muscular endurance. The more repetition someone could perform, the stronger their muscle endurance was.

Exercises are often defined as training processes. Therefore this would need a full body workout if possible, exercise should be of different parts. It should not only concentrate on muscles but also on lungs and hearts.

Therefore exercising the whole body is important and training at would also imply that it would be good in the long run for a person's body

Therefore, option D is the correct option.

what is one reason why some western cities may not have developed good public transportation systems

Answers

Answer:

A reason for not developing good public transportation systems in some of the western cities is that tectonic activity.

Explanation:

In some parts of the West, tectonic activity presents a massive problem when it comes to developing and maintaining infrastructure, such as transportation infrastructure. There is a transform plate boundary between the North American plate and Juan de Fuca plate, causing constant stress on the crust, resulting in regular earthquakes, but also the formation of faults.

This has prevented multiple cities to create good public transportation, or the one they have is a basic one. It is simply not safe and economically unjustifiable to create underground transportation infrastructure as many big cities have because the earthquakes and cracks in the crust will destroy it, and more importantly, millions of lives will be put at stake each day.
