To find the value of x, we can take the inverse sine of both sides. Let's do just that:
Note: This x is in radians. Your answer is
x = 0.3 rad or, depending on the instructions provided, it could be in degrees as
x = 15.47°.
400 = 8b + y (subtract 8b from each side)
<u>-8b -8b </u>
400 - 8b = y
The answer is y = -8b + 400
i isolated y, which means i left it alone on one side of the equation
Let n be the number of sides of a polygon.
To solve for the sum of the interior angles:
(n-2) x 180°
To solve for the measure of each interior angle of the polygon
[(n-2) x 180°] / n
To solve for the measure of each exterior angle:
360° / n
The sum of the exterior angles is always 360°

C and B is proportional relationships , because the proportional relationships always start at zero and the line must be straight !
