Question

the angles of quidilateral are 2x+15,3x+5,x+20 and 80+x find the measurement of angle​

Answer 1

$\bold\red{Answer:}$

Property used = Sum of angles is 360°

2x+15+3x+5+x+20+x+80=360

7x+120=360

7x=240

x=$\blue{34.285°}$

1st angle = 2(34.285)+15=$\red{83.5714°}$

2nd angle =3(34.285)+5=$\pink{107.8571°}$

3rd angle = (34.285)+20=$\green{54.2857°}$

4th angle = (34.285+80)=$\orange{114.2857°}$

hope it helps. ☆☆☆
