Answer:
Each side of the triangle is 4cm and each angle is 60 degrees
Step-by-step explanation:
First you must know that for remarkable angles: cos (0) = 1, cos (π) = - 1, cos (π / 2) = 0, cos (3π / 2) = 0, cos (2π) = 1. Then, by simple substitution in the given formula, you can find the solutions of x. Which for the interval [0, 2π) are: x = π, x = pi divided by two and x = three pi divided by two.Attached solution.
I think that the answer would be 6+-8 because it equals -2 and 6-(-8)= -2
