Answer:
The measure of an exterior angle is found by the following formula: Aˆ0B=^AB-^CD2. An interior angle has its vertex at the intersection of two lines that intersect inside a circle. The sides of the angle lie on the intersecting lines. You can find a measure of an exterior angle of a regular polygon with
N sides. It is equal to 360
o
N
.
Step-by-step explanation:
Angles of a general polygon (exterior and interior) with more than 3 sides are not defined by the lengths of its sides.
However, we can calculate the sum of all interior or exterior angles of any convex polygon. It equals to 360
o
.
It can be proven geometrically since each exterior angle describes a rotation by some angle and a sum of all exterior angles describes a rotation by full angle of
360
o
. So, if all exterior angles are equal, like in a regular polygon, each one equals to 360
o
N
.
It can also be defined with some algebraic calculations based on the fact that a sum of all interior angles is (
N
−
2
)
⋅
180
o
.
Dividing the above by N
we will obtain a value of an interior angle: (
N

)

Therefore, exterior angle of a regular polygon is 180

20/50=2/5=0.4=40%
2/5 or 0.40 or 40%
They're all equal.
Hope this helps :)

Have a brilliant day mate-Lily ^_^
Answer:
I hope my drawing explains well lol... h = 16
Step-by-step explanation:
So basically first you need to find x (the one in the drawing), by doing so, you just have to use the formula,
You substitute in the speed and the time given,
Then, you use the Pythagorean theorem,
