As we know

the sum of measures of angles of quadrilateral is 360

so

x+x+30+x-10+2x=360

5x+20=360

5x=340

x=68

greatest angle

=2x

=2×68

=136

Khushi100100: but answer is ...136°... is the greatest ...
asna7: sum of the angle is 360
Khushi100100: oh thanx ...
Thatsomeone: sorry i mistaken
Khushi100100: ok np

total angle = 360
x+(x+3)+(x-10)+2x=360
3x+(x+30)+(x-10)= 360
3x+(x+30)+x=360+10=370
4x+x=370-30=340
5x=340
x= 340÷5
x=68
greatest angle is 2x
2x= 2×68
=136 digre

Khushi100100: thank you mam ... very much
asna7: wlcome
asna7: welcome
