Multiply 80 by 5/8ths. 
80*5/8=50
        
             
        
        
        
(a) Using the table, give the values fo rthe inverse
1) original table of values:
x      1     2     3    4    5
f(x)   0     1     1    5    3
2) The inverse of the function is obtained by exchanging x and f(x), this is:
                   ( x, f(x) ) → ( f(x), x)
3) So, the table of values of the inverse of the given function is:
x          0    1     1      5     3
f⁻¹ (x)   0     1     2     3     4
(b) Is the inverse a function?
No, the inverse is not a function, since the table of the inverse shows that the x -value 1 has two different images.
This ambigüity is opposite to the definition of a function, which requires that any input value has only one output. For that reason, the inverse is not a function. You cannot tell whether the image of 1 is 1 or 2, because both are images of the same value.
        
             
        
        
        
Answer:
83°
Step-by-step explanation:
WZ is a straight line. Angles at a straight line add up to 180°.
180 - 97 =83°
