Respuesta :
The value of x according to the information given about the trapezoid is; 5.375
Isosceles trapezoid
The sum of angles in a trapezoid like other Quadrilaterals is; 180°.
However, since the trapezoid is Isosceles, Top angles are equal and bottom angles are equal too.
Hence, we have;
- 2(9x) + 2(7x+4) = 180
- 18x + 14x +8 = 180
- 32x = 172
- x = 172/32
- x = 5.375
