The height of the flagpole is: 12 ft.
<h2>
Step-by-step explanation:</h2>
Let the height of the flagpole be: x ft.
Now, we can model this problem with the help of a right angled triangle such that the hypotenuse of the triangle is: 20 feet
and one of the leg of the right triangle is: 16 feet
Now, in order to find the other leg i.e. x we need to use the Pythagorean Theorem.
i.e.
But the height can't be negative.
Hence, we get:
8x+6y=10
6y=10-8x
y=(10-8x)/6
Try using 1070 degrees as the sum of the interior angles of a convex polygon, we get:
1070 =[n - 2] x 180 (n = number of sides)
1070 =180n - 360
180n =1070+360
180n =1430
n = 1430 / 180
n = 7.94 number of sides.
Round the number up to 8 since 7.94 isn’t whole.
So, the convex polygon is an octagon with sum of its interior angles:
[8 - 2] x 180 =1080 degrees.
I think it’s C but it might be D
On 300 rolls of one dice you expect 75 fours but, as with all games of chance, you cannot be certain at all
