What is the measure of an interior angle in a regular octagon?

1 answer:

5 0

To find the interior angle of any regular polygon you can use the formula $\frac{(n-2)*180}{n}$ where n is the number of sides
So, $\frac{(8-2)*180}{8} =135$
The measure of an interior angle in a regular octagon is 135

Aleonysh [2.5K]

Answer:

Correct answer: Hmax = 22.11 m

Step-by-step explanation:

The subject of this problem is a vertical shot upwards, to which the following formula applies:

V₀² - V² = 2 · g · H where is:

V₀ - initial velocity

V - final velocity

g = 10 m/s²

H - final height

Given:

V₀ = 69 ft/s = 21.03 m/s

V = 0 m/s

Hmax = ?

V₀² = 2 · g · Hmax ⇒ Hmax = V₀² / 2 · g

Hmax = 21.03² / 2 · 10 = 442.26 / 20 = 22.11 m

Hmax = 22.11 m
