I don't know why the first question is cut off..

1) b cause range is f(x) or y values

2) d cause 64-9 = 55, cube root of 27 is 3 and 3^2=9

3) 35 cause 90-55=35, angle 2 and 5 are the same

Can't help you with the first unless I can see the y values....these deal with  the range

 

 

Second one

 

8^2  - 27^(2/3)   =

64   -  [27^(1/3) ] ^2                   note..... {27^(1/3)  is the cube root of 27  = 3 }

64  - [ 3 ]^2  =

64 - 9 =

55

 

 

Last one 

Angle 2  = 55

Angle 3 is a right angle  = 90

Angles  2 + 3 + 4  = 180  ....so.....

 

55 + 90  + Angle 4  = 180

145 + Angle 4  = 180      subtract 145 from both sides

Angle 4 =  180 - 145  =    35  (degrees)
