The sum of the interior angles of a quadrilateral is 360 degrees.
So, the interior angles of points B and D must add up to 360 degrees.
Therefore, we have the equation:
(3x-7) + (x+15) = 360
Simplifying the equation:
4x + 8 = 360
4x = 360 - 8
4x = 352
x = 352/4
x = 88
Therefore, the value of x is 88.
the interior angle of point b measures (3x-7) degrees and the interior angle of point d measures (x+15) degrees. what is the value of x?
