Pls solve the right way then I’ll give you 15pts

x=27

Step-by-step explanation:

Aight so the angle of line AB equals 180 degrees. You have 36 degrees plus the right angle (90 degrees) which gets you 126 degrees. Subtract 126 from 180 and you get 54, the remaining value. So if 2x=54, then divide both sides by 2 to get x=27. that should be it

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)
