A) A rhombus
B) A parallelogram
C) A trapezium
D) A kite
Correct Answer: C
Solution :
Let the angles be \[3x,\text{ }7x\text{ },\text{ }6x\] and\[4x\]. \[\therefore \] \[3x+7x+6x+4x={{360}^{o}}\] or \[20x={{360}^{o}}\] or \[x={{18}^{o}}\]. The angles are \[{{54}^{o}},{{126}^{o}},{{108}^{o}}\]and \[{{72}^{o}}\]. We see that adjacent angles are supplementary but opposite angles-are not equal. Clearly, it is a trapezium.You need to login to perform this action.
