Answer:
-

- Dimensions of the flag:

- Area of the flag:

Step-by-step explanation:
<em><u>The missing figure of the exercise is attached.</u></em>

We know that the perimeter of the triangle is given by:

Where "s" is the side lenght of the triangle.
Solving for "s", we get:

Therefore, if the perimeter of the triangle is 126 inches, its side length is:

Since
, we know that "s" in feet is:

The area of a rectangle can be calculated with this formula:

Where "l" is the lenght and "w" is the width
We can observe in the figure that the lenght and the width of the flag are:

Then, the dimensions of the flag are:

And the area is:

Let the height of the rocket be x, then
tan theta = h / 1 mile
h = 1 tan theta miles
But 1 mile = 5280 feets
Therefore, the height in feet = 5280 tan theta.
Answer:
9/14
Step-by-step explanation:
You multiply the two fractions. So 5/7*9/10, you just multiply across. This would give you 45/70. Then, after simplifying, this fraction is 9/14. So, Sean ran 9/14 of a mile on Sunday. Hope this helps, Sorry if im wrong!!
