Can anybody help me please?! I'll give brainlest for correct answer​

Yes I can help you. what do you want the help for?

AOB = 65 degree angle

DOE = 35 degree angle

AOC = 90 degree angle

EOB = 115 degree angle

DOB = 80 degree angle

Step-by-step explanation:

Use the protractor to measure. Each dash around the edge is equal to 5 degrees.

i do not know this sorry : (

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)
