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
+128456 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)
