Question

50cos38/sin52 решить

Answer 1

Cos38 - одно и то же, что и sin52 (свойство такое)
т.е. 50*sin52/sin52 = 50*1 = 50

Answer 2

$\frac{50Cos38}{Sin52} = \frac{50Cos(90 - 52)}{Sin52} = \frac{50Sin52}{Sin52} = 50$

Answer 3

To solve this problem, we will use the trigonometric identity:

cot(x) = cos(x)/sin(x)

where cot(x) is the cotangent of angle x.

Using this identity, we can rewrite the expression 50cos(38)/sin(52) as:

50 * cot(52) * cos(38)

Now, we just need to plug in the values and simplify:

50 * cot(52) * cos(38)

= 50 * (cos(52)/sin(52)) * cos(38)

= 50 * cos(52) * cos(38) / sin(52)

= (50 * cos(52) * cos(38)) / sin(52)

So the final answer is (50 * cos(52) * cos(38)) / sin(52). This is an exact expression, but if you need a numerical approximation, you can substitute the values and evaluate using a calculator.
