Answer: the value of x is 45 degrees.
Explanation:
When tanx = 1, we want to determine the value of x.
To determine the value of x, we would find that tan inverse of 1. It is represented as
Tan^(-1) = 45 degrees.
This is found by looking at the trigonometric table or using a calculator. With a calculator, press shift + tan and press 1, the result would be 45 degrees
