Y=??

y = 70 degree's

Step-by-step explanation:

180 is a straight line therefore the equation would read ...

180 = 110 + y

subtract 110 from both sides ...

70 = y

y = 70

Step-by-step explanation:

This is a supplementary angle so:

y + 110 = 180

y = 180 - 110

y = 70

since your problem is x^4 = 81, what you have to undeo is the "to the fourth power" part.

the inverse (opposite operation) of "to the fourth power" is "to the fourth root".

  (x^4) ^ ¼   = 81 ^ ¼  

  81 = 3^4     so (3 ^ 4) ^ ¼   =   3 ^ 1   = 3

by hand: (3 ^ 4) ^ ¼   =   3 ^ (4 x ¼) = 3 ^ 1   = 3   (when you take a power to a power, multiply the exponents.)

or, do it by calculator. one way of finding the fourth root is to use ^ (1/4)
