Answer 1

Answer:

Step-by-step explanation:

when two chor intersect each other 4 angles are formed

by the theorem intersection of  two chord

∠1 + ∠3 =78

∠2 =half of ∠1 + ∠3 =78

∠2= 19 degree

these example is solve by theorem of intersection of two chord of 10 standard.

Answer 2

angle 1 +angle 3=78
angle 1= angle 3(vertically opposite angles)
angle 1+angle 1=78
2(angle 1) = 78
angle 1= 78/2
angle 1=39=angle 3

angle 3 + angle 2= 180(linear pair)
39+angle2 =180
angle 2 = 180-39
angle 2 = 141

hope it helps!
