Answer:
C
Step-by-step explanation:
tanx=17/100
so do the inverse so it would be tan^-1 (17/100)= degrees

Answer:
Step-by-step explanation:
Since log is defined by all positive real  numbers 
therefore domain is all  positive real number that is ( 0,∞)
Range is given by real numbers 
inverse of the given function is  (10^x)/7
Whose domain is all real numbers and range is all positive real number 
And since we know that domain of function and range of its inverse 
& range of a function and domain of its inverse is same 
which we are getting in the problem
so  answer is justified
