Answer 1

Answer:

other questions will solve with  the same processes

Step-by-step explanation:FIGURE NO. 1

∠1+∠2+∠3=180°(angle sum property of triangle)

60°+50°+∠3= 180°

110°+∠3=180°

∠3=180°-110°

∠3=70°

now ......................

∠3+exterior angle(x)=180° (angle sum property of triangle )

70°+x=180°

x=180°-70°

x=110°

FIGURE NO. 2

40°+80°+∠3= 180°(ANGLE sum property of triangle )

120°+∠3=180°

∠3=180°-120°

∠3=60°

now,

angle Y +∠3=180°(ANgle sum property of line )

y+60°=180°

y=180°-60°

y=120°
