Answer:
See Below
Explanation:
angle BAK = 128
Find KAS
180 - 128 = 52
KAS = 52
find BKA and ABK
360 -128 = 232
232/2 = 116
BKA =116
ABK = 116
find AKS
180 - 116 = 64
AKS =64
Now you have KAS and AKS
add together and subtract sum from 360 to find BSK
52 + 64 = 116
360 - 116 =244
Let me know if incorrect, plz.
Hope this helps=)
