Question

Треугольник A BC угол C прямой угол А 60 градусов это 28 сантиметров найти АС

Answer 1

Думаю так нужно решить

Answer 2

Угол В=30 градусов
тогда за свойством катет что лежит против угла в 30 градусов имеем, что АС=14 см

Answer 3

Solution:

Given that triangle ABC has a right angle at C and angle A is 60 degrees, we can use trigonometric functions to find the length of side AC.

We can use the trigonometric function tangent (tan) to find the length of side AC. The tangent of an angle in a right-angled triangle is the ratio of the length of the opposite side to the length of the adjacent side.

Using the given information, we can use the tangent function to find the length of side AC:

tan(A) = opposite/adjacent

tan(60) = AC/BC

We also know that BC = 28 cm.

Now, we can solve for AC:

AC = BC * tan(A)

Substituting the given values:

AC = 28 * tan(60)

Calculation:

AC = 28 * tan(60) AC ≈ 28 * 1.732 AC ≈ 48.976

So, the length of side AC is approximately 48.976 centimeters.
