Answer: 
Step by step:

(Used a table of common angles)
120° because 155-35=120 since IJZ is inside the IJK so you would have to subtract the ZJK from the IJZ.
Answer:
3/2
Step-by-step explanation:
Apply exponent rule: a^-1 = 1/a
(2/3)^1 = 1/2/3
Apply the fraction rule: 1/a/c = c/b
3/2
Answer:
linear pair
Step-by-step explanation:
the sum of linear pair angles is 180 degree.
so if we apply 16 in place of x in both equations and add them we get 180
