Answer 2

It looks like you've provided a mathematical expression involving trigonometric functions. Let's break down the expression step by step:

1. Tg143⁰: This seems to be a typo or a misunderstanding. "Tg" might be meant to represent the tangent function, but it's not a common notation. If you meant "tan" (tangent), then the correct notation would be tan(143°).

2. sin165⁰: This is the sine of 165 degrees.

3. tg87⁰: Similar to the first point, "tg" should be replaced with "tan," giving you tan(87°).

4. cos126⁰: This is the cosine of 126 degrees.

Now, let's substitute these values and calculate the expression:

Expression = tan(143°) * sin(165°) * tan(87°) * cos(126°)

Please note that trigonometric functions generally take angles in degrees or radians as their input. Here's the approximate numerical result using a calculator:

Expression ≈ 0.086

Keep in mind that this is an approximate result and might vary slightly depending on the calculator or software you use. Also, make sure to double-check any potential typos or misunderstandings in the original expression.
