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

we have

substitute



therefore
Polygon Y's area is one ninth (1/9) of Polygon X's area
Answer:
Step-by-step explanation:
Use a number line to help, or a tape diagram.
Answer:
6x+3y-15
Step-by-step explanation:
take the x's add them up. take the y put it after the answer of the x's then subtract the y. (im just waffling)
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,
(Alternate interior angles)
For any angle
,
= side opposite to angle/side adjacent to angle

Put 

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