Answer 2

The value of x=60

Step-by-step explanation:

Let a quadrilateral ABCD in which

Angle A=x+20

Angle B=x-20

Angle C=2x+5

Angle D=2x-5

Sum of angles of quadrilateral ABCD=360 degrees

$\angle A+\angle B+\angle C+\angel D=360$

Substitute the values

$x+20+x-20+2x+5+2x-5=360$

$6x=360$

$x=\frac{360}{6}$

$x=60$

Hence, the value of x=60
