Answer:1 5/6

Step-by-step explanation:Its because 2 x 3 = 6 which is the denominator. That means you have to multiply 2 by 2 which gives you 4. and 1/2 of a 6th is 3/6. so 2 3/6 - 4/6 = 1 5/6

Polygon Y is a scaled copy of Polygon X using a scale factor of \dfrac13 3 1 start fraction, 1, divided by, 3, end fraction. P

emmainna [20.7K]

Answer:

Polygon Y's area is one ninth (1/9) of Polygon X's area

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its areas is equal to the scale factor squared

In this problem

Let

z-----> the scale factor

a-----> Polygon Y's area

b----> Polygon X's area

$z^{2}=\frac{a}{b}$

we have

$z=\frac{1}{3}$

substitute

$(\frac{1}{3})^{2}=\frac{a}{b}$

$\frac{1}{9}=\frac{a}{b}$

$a=\frac{1}{9}b$

therefore

Polygon Y's area is one ninth (1/9) of Polygon X's area

A plane is descending onto the runway with an angle of depression of 55°. If it has 2.8 miles to go before landing (hypotenuse),

nalin [4]

Answer:

Option C is correct

Step-by-step explanation:

Given: A plane is descending onto the runway with an angle of depression of 55°. Also, it has 2.8 miles to go before landing.

To find: current altitude of the plane

Solution:

Consider the attached image.

In ΔABC,

$\angle ACB=55^{\circ}$ (Alternate interior angles)

For any angle $\theta$ ,

$tan \theta$ = side opposite to angle/side adjacent to angle

$\tan C=\frac{AB}{BC}$

Put $\angle C=55^{\circ}\,,\,BC=2.8\,\,miles$

$AB=2.8\,\tan 55^{\circ}=3.999\approx 4\,\,miles$

So, the current altitude of the plane is 4 miles.
