Question

Abcd is a trapezium what is the value of x? If a=110and b=x

Answer 1

I think this is not possible to find , if it is not an isosceles trapezium.

Because in simple trapezium ,only one pair of opposite sides are parallel , no side , diagonal, angles are congruent ( equal).



Thanks.

Answer 2

Answer:

70

Step-by-step explanation:

In a trapezium, AB || CD

∴ sum of adjacent angles =180°

∠D+∠A=180°

∠A=180°−∠D=180°−110°

∠A=70°
