Answer:
60+<1+ 55=180 linear pair angles
<1 =65
<1+2x+105=360 (sum of angles of quadelatral =369)
65+105+2x=360
175+2x =360
2x=360-175
2x=190
x= 95

Answer:
x = 95°
Step-by-step explanation:
Let angle opp. to 105° be y, then
60° + 55° + y = 180 ° [ Linear pair]
y = 180° - 115°
y = 65°
Now since sum of all the angles of a quadrilateral is 360° , therefore
105° + y + x + x = 360°
105° + 65° + 2x = 360°
2x = 360° - 170°
2x = 190°
x = 190° / 2
x = 95°
