Question 1183982
The sum of the angle measures of a quadrilateral is 360 degrees.
 And the shape is a trapezoid at the bottom corners is 1/2x to the left and 1/2x to the right,
 and the top corners are both "x" now what is the value of "x".
 Also what would 1/2x be if you found the value of "x".
:
the 4 angles add up to 360
.5x + .5x + x + x = 360
3x - 360
x = 360/3
x = 120 degrees
:
 Also what would 1/2x be if you found the value of "x".
.5(120) = 60 degrees
