The sum of the interior angles of any polygon is always . . .

(180 degrees ) times (2 less than the number of sides in the polygon) .

It doesn't matter whether the polygon is regular, haphazard, convex,
or all mangled and squashed etc. The only thing that matters is
how many sides it has.

The octagon has 8 sides. So the sum of interior angles is . . .

(180 degrees) times (8 - 2) = (180 x 6) = 1,080 degrees

Which statement is true about the difference 2 square root of 7 − square root of 28 ?

boyakko [2]

I'll go slow:

$2\sqrt 7 - \sqrt{28}$

$=2 \sqrt 7 - \sqrt{4 \cdot 7}$

$=2 \sqrt 7 - \sqrt{4} \cdot \sqrt{7}$

$=2 \sqrt7 - 2 \sqrt 7$

$=0$

Answer: B rational and equal to 0.

An ant looks up to the top of a tree at an angle of elevation of 40 degrees. If the ant is 30 feet from the base of the tree, wh

Alborosie

For the answer to the question above, this is a right triangle problem using the tangent function.
Tan(x) = Opposite (O) / Adjacent (A) 
x = 40 degrees 
A = 30 ft 
Solve for O 
O= Tan (x) * A 
O = Tan (40) * 30 
Use your calculator or whatever method to get the tangent of 40 degrees (which is .84) 
O = .84 * 30 
O = 25.2 Ft
