True or false. all rectangles are similar because they have congruent corresponding angles?

All rectangles have 90 degree angles on all four sides.
The definition of similar is proportional to each other.
One rectangle can have length=8 and height=4 and another can have length=34 and height =5, and they would not be proportional.
False.

True, there all the same just different sizes and are rotated differently.

Option D

Plane B because it was 9.33 miles away

Step-by-step explanation:

This problem can be simulated by two right triangles:

For Plane A, we have the elevation angle . We know that the height is 6 miles.

To find the horizontal distance we use the function

By definition:

In this case:

hypotenuse=distance from the airport

Then:

distance from the airport: 8.64 miles

For Plane B, we have the elevation angle . We know that the height is 6 miles.

To find the distance we use the function

By definition:

In this case:

Hypotenuse=distance from the airport

Then:

distance from the airport: 9.33 miles

Finally the answer is the option D.
