Step-by-step explanation:
It's going up by 4 each time.
Exterior angles of polygons always add up to 360 degrees.
A pentagon has 5 sides, so divide 360 degrees by 5 sides.
360/5 = 72
One exterior angle of a regular pentagon (all 5 sides and angles are equal) is 72 degrees.
Sin of an angle = opposite side / hypotenuse
sin(30) = square root of (x/2) / 4x
1/2 = square root of (x/2) / 4x
1/2 = square root of ((x/2)/16x^2)
1/2 = square root of (1/32x) / ^2
1/4 = 1/32x / *32x
8x = 1
x = 1/8
The conclusion drawn from the study is instance because the sample is homogenous and an experimental study was performed.
<h3>What is an experimental study?</h3>
An experimental study deals with a dependent variable and there is a dependent variable.
Also, a control is used to establish the validity of the results.
The dependent variable is the level of softness after treatment while the independent variable is the type of water softener used.
The conclusion drawn from the study is instance because the sample is homogenous and an experimental study was performed.
