Answer:
17. angle DAB=118º
18. angle DAB=126º
Step-by-step explanation:
The angle A should be 180º-85º-33º(cause the total angle in a triangle is 180º)
So you will get 62º as the angle of A.
And what the question ask is angle of DAB，so again 180º-62º=118º(A straight line is 180º)
Same goes to question 18，use 180º to minus the two angle given，you get 54º ，and then 180ºminus 54º again，the answer is 126º

Answer:
f(0.1) =
Step-by-step explanation:
Plug x = 0.1.
Therefore f(0.1) = ln (log (0.1)).
0.1 = 10^(-1), and by the definition of log, log 0.1 = -1.
Now f(0.1) = ln (-1).
By Euler's identity, e^(i pi) = -1.
So ln (-1) would be i pi.
f(0.1) =
