A plane is flying at an altitude of 25,000 m. From the pilot, the angle of depression to the airport tower is 30°. How far is th

maria [59]

The question is modelled as shown in the diagram below

We have the angle, 30° and we know the length of the side opposite the angles, 25000 feet. We are looking for the ground distance between the plane and the tower. We will use the trigonometry ratio of Tan

$tan(x)= \frac{opposite}{adjacent}$
$tan(30)= \frac{25000}{y}$
$y= \frac{25000}{tan(30)}$
$y=43301.27019$

The distance between the point directly beneath the plane and the tower is 43301.3 feet (rounded to 2dp)

Khalil has a game board as shown below, which is a square with 20 cm sides. The area of the largest circle is 314

Elenna [48]

Answer:

The probability of scoring 1, 3, or 5 points with one randomly thrown dart is equal to divide the area of the largest circle by the area of the square game board

step 1:

Find the area of the square game board

"A=b^{2}"

we have

b=20cm

"substitute"

A=20^{2}

=400cm²

step 2:

Find the probability

P=314/400

=0.785

=0.785 x 100

=78.5%
