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
on (1.33) = 50.5.
