Answer 1

Answer:

x=35

Step-by-step explanation:

Here AB||CD and AD is transversal.

So,∠ADC+∠BAD=180˚      [co-interior angles]

→2x+50+2x-10=180

 4x+40=180

 4x=140

  x=35

Answer 2

SOLUTION

A trapezium is a Quadrilateral with one pair of opposite sides parallel.

A trapezium is a Quadrilateral with one pair of opposite sides parallel.Using co- interior angles, we can see that a trapezium has two pairs of adjacent supplementary angles.

So,

∠A +∠D= 2x+50+2x-10= 180°

=) 4x+40= 180°

=) 4x= (180-40)°

=) 4x= 140°

=) x= 140°/4

=) x= 35°

Now,

∠A= 2x+50

=) 2× 35°+ 50

=) 70+50

=) 120°

∠B= 2x-10

=) 2× 35- 10

=) 70-10

=) 60°
