Answer:
A x-198,y-99
Step-by-step explanation:
since sin p/h you can say
perpendicular is 99
and hypotenuse is x
sin 30=99/x
x=198
and cos is b/h
base is y
and hypotenuse is x
cos 30=y/198
y-99
Answer:
The measure of one angle of a regular convex 20-gon is 162°
Step-by-step explanation:
* Lets explain how to solve the problem
- A convex polygon is a polygon with all the measures of its interior
angles less than 180°
- In any polygon the number of its angles equal the number of its sides
- A regular polygon is a polygon that is all angles are equal in measure
and all sides are equal in length
- The rule of the measure of an angle of a regular polygon is
, where m is the measure of each interior
angle in the polygon and n is the numbers of the sides or the angles
of the polygon
* Lets solve the problem
- The polygon is convex polygon of 20 sides (20 angles)
- The polygon is regular polygon
∵ The number of the sides of the polygon is 20 sides
∴ n = 20
∵ The polygon is regular
∴ All angles are equal in measures
∵ The measure of each angle is
∴
∴
∴
∴ m = 162
∴ The measure of one angle of a regular convex 20-gon is 162°
