Question

the interior angles of a quadrilateral are 2x+15,2x-5,3x+75,3x-25 find x and largest exterior angle​

Answer 1

interires anglea of quadrilateral=360

2x+15+2x-5+3x+75+3x-25=360

10x=360-60

10x=300

x=30

angle a=2x+15=2×30+15=75

angle b=2x-5=2×30-5=55

angle c=3x+75=3×30+75=165

angle d=3x-25=3×30-25=65
