Question

5tg(73)/ctg(17) Надите пожалуйста значение выражения

Answer 1

Tg73=tg(90-17)=ctg17
5ctg17/ctg17=5))

Answer 2

To calculate the value of the expression, we need to first understand the trigonometric functions used in the expression:

1. "tg" stands for the tangent function, which is commonly denoted as "tan." The tangent of an angle is the ratio of the length of the opposite side to the length of the adjacent side in a right-angled triangle.

2. "ctg" stands for the cotangent function, which is the reciprocal of the tangent function. It is defined as the ratio of the length of the adjacent side to the length of the opposite side in a right-angled triangle.

Since the value of angles like 73 degrees and 17 degrees are not standard angles that we can easily find the exact values for, we'll need to use a calculator to approximate the result.

Let's use a calculator to find the approximate value of the expression:

1. Calculate tg(73) ≈ tan(73°) using a calculator.
2. Calculate ctg(17) ≈ 1 / tan(17°) using a calculator.
3. Divide tg(73) by ctg(17).

Keep in mind that the result will be an approximation due to the use of calculator functions.

Approximately, the value of the expression 5tg(73)/ctg(17) is:

5 * (tan(73°)) / (1 / tan(17°)) ≈ 23.6506

So, the value of the expression is approximately 23.6506.
