Given ABC where AC = 7.12 cm, BC = 7.12 cm, and AB = 7.12 cm, then the mZB =
С
8

The measure of m∠B = 60°

Step-by-step explanation:

The given parameters are;

The length of the sides of ΔABC includes;

Side AC = 7.12 cm

Side BC = 7.12 cm

Side AB = 7.12 cm

Therefore, given that all the sides of the triangle are equal, we have that the triangle is an equilateral triangle

The measure of the each interior angle of an equilateral triangle = 60°, by definition of equilateral triangle

∴ The measure of m∠B = 60°.

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)
