Question

x-20 degree +3x+20 degree ​

Answer 1

Answer:

Step-by-step explanation:

x-20+3x+20=180

4x=180

x=45°

Answer 2

Answer:

The difference between the greatest and the smallest angle of the given quadrilateral is 65°

Step-by-step explanation:

The angles of quadrilateral are:

Angle 1 =  

Angle 2 =  

Angle 3 =  

Angle 4 =  

Sum of all angles of quadrilateral = 360 °

So, 3x+15+x+20+2x+30+3x-20= 360

3x+15+x+20+2x+30+3x-20= 360

9x+45=360

9x=360-45

9x=315

x=35

Angle 1 =

Angle 2 =  

Angle 3=

Angle 4 =

Difference between the he greatest and the smallest angle = 120-55= 65

Hence the difference between the greatest and the smallest angle of the given quadrilateral is 65°
