The Tan inverse on 1.3 repeating is 50.5.

The inverse tangent function, often denoted as tan-1 or arctan, is used to find the angle whose tangent equals a given value.

In this case, you want to find the arctan of 1.3 repeating.

To solve this, you can convert the repeating decimal into a fraction.

Let x = 1.3 repeating.

Multiply both sides of the equation by 10 to get 10x = 13.3 repeating.

Next, subtract the original equation from the new equation to eliminate the repeating part: 10x - x = 13.3 - 1.3, which simplifies to 9x = 12.

From here, divide both sides by 9 to solve for x, yielding x = 12/9 = 1.33.

Now, you can find the arctan of 1.33.

Using a calculator or trigonometric table, you will find that
tan^(-1) on (1.33) = 50.5.
