Question

СРОЧНО!!!!Знайдіть радіус кола описаного навколо трикутника у якому сторона довжиною 2 см лежить прот​и кута 30°

Answer 1

Ответ:

Объяснение:

(Кажется в условии не дописано что : "..лежит против угла 60° ")

Если так, тогда:

Из следствия к теореме синусов :

а / sinα=2R  

2R = 2/sin 60°  

2R=2 ∙ 2/√3 = 4/√3

R=2/√3  

Answer 2

Finding the Radius of the Circumscribed Circle

To find the radius of the circumscribed circle around a triangle, we can use the following formula:

Radius = (Side Length / (2 * sin(Angle)))

In this case, we have a triangle with a side length of 2 cm and an angle of 30°. Let's plug these values into the formula:

Radius = (2 cm / (2 * sin(30°)))

To calculate the sine of 30°, we can use a calculator or reference table. The sine of 30° is 0.5. Plugging this value into the formula, we get:

Radius = (2 cm / (2 * 0.5)) = (2 cm / 1) = 2 cm

Therefore, the radius of the circumscribed circle around the triangle is 2 cm.
