Answer:

I think the answer is Option D, 135 degrees.

Since the angles of all of the octagon combined is 1080, divide that by 8 to get 135 which means that all 8 angles are 135 degrees.

Answer:

D) 135 degrees

Step-by-step explanation:

Firstly, all sides of a regular octagon are equal, thus, the angles would be too. Since each exterior angle is supplementary to the the interior angle, in total it would be 180 degrees. We know that the sum of the angles would have to be 1080 degrees, so we only have to divide by 8.  

1080/8 = 135 degrees

FinnZ [79.3K]

Answer:

The length of the hypotenuse ≈ 39.7 cm

Explanation:

Since the given triangle is a right-angled triangle, this means that we can apply the Pythagorean theorem.

The equation for Pythagorean calculation is:

(hypotenuse)² = (first leg)² + (second leg)²

In the given, we have:

first leg = 30 cm

second leg = 26 cm

Substitute with the givens in the above equation to get the hypotenuse as follows:

(hypotenuse)² = (30)² + (26)²

(hypotenuse)² = 1576

This means that:

either hypotenuse = √1576 = 39.69 ≈ 39.7 cm ..........> accepted

or hypotenuse = -√1576 = -39.69 ......> rejected as length can't be negative

Hope this helps :)

Answer:

4000 m^{3}

Step-by-step explanation:

V = 1/3(Bh)  where B is the area of the base and h is the height of the pyramid

B = 20(20) = 400      h = 30

V = 1/3(400)(30) = 4000 m^{3}
