When Carla solved for the height from the ground to the point where the ladder
Westkost [7]

Answer:

<em>See explanation</em>

Explanation:

Given

Represent the vertical angle with \theta

\theta = 75

The question has incomplete details because the length of the ladder is not given; neither is the distance between the ladder and the wall given.

<em>See attachment for illustration</em>

So, this solution will be based on assumptions.

Represent

- The height from ground to the top of the ladder with y

- The length of the ladder with L

- The distance between the ladder and the wall with x

Carla could solve for y in any of the following ways:

1. Tan formula

tan \theta = \frac{opp}{adj}

In this case:

tan \theta = \frac{x}{y}

Multiply both sides by y

y * tan \theta = \frac{x}{y} * y

y * tan \theta = x

Divide both sides by tan

y   = \frac{x}{tan \theta}

y   = \frac{x}{tan 75}

This can be used if the distance (x) between the ladder and the wall is known.

Assume x = 15

y   = \frac{15}{tan 75}

y = 4.02

2. Cosine formula

cos \theta = \frac{adj}{hyp}

In this case:

cos \theta = \frac{y}{L}

Multiply both sides by L

L * cos \theta = \frac{y}{L} * L

Lcos \theta = y

y = Lcos \theta

y = Lcos75

This can be used if the length (L) of the ladder is known.

Assume L = 15

y = 15 * cos75

y = 3.88

Assuming that the long term rate of displacement along the San Andreas Fault (about 3.5 cm/year) remains the same and that the l
Kisachek [45]

Answer:

17.71 years

Explanation:

  • As the crust of the San Andrea is continuously moving due to the tectonic activity and is the main manifest of the tectonic boundary of the North America and the pacific plate. This fault along with the pacific plate will move towards the Los angles and eastern San Francisco as it moves about 3.5 cm per year.
  • As  1 km equals to about 100 000 cm , then the distance of 620 km =  62, 000,000 cm  and 62,000,000 will be divided by 3.5 equal to  17. 71 years to collide with the eastern side.

How is a representative democracy different from a direct democracy? ​
Bingel [31]

Answer:

In representative democracy, citizens elect representatives, who in turn represents their interests in the elected government. The vast majority of democracies in the world are representative.

In a direct democracy, citizens have more direct ways to participe in the government, and in the making of the laws of the country or region. There are very few places in the world where direct democracy is the norm, Switzerland being perhpas the most noteworthy example.

How is latitude measured?
NeX [460]

Lines of latitude measure north-south position between the poles. The equator is defined as 0 degrees, the North Pole is 90 degrees north, and the South Pole is 90 degrees south. Lines of latitude are all parallel to each other, thus they are often referred to as parallels. Your latitude can be calculated by measuring the angle of the sun.
