Answer 2

Calculating the Perimeter of a Rhombus with an Angle of 60° and Side Length AC of 15.3 cm

To find the perimeter of a rhombus when the angle B is 60° and the side length AC is 15.3 cm, we can use the properties of a rhombus to calculate the perimeter.

A rhombus is a special type of quadrilateral where all four sides are of equal length. Additionally, the opposite angles of a rhombus are equal, and the diagonals bisect each other at right angles.

Given: - Angle B = 60° - Side length AC = 15.3 cm

Calculating the Perimeter

To calculate the perimeter of the rhombus, we can use the formula: Perimeter = 4 * Side Length

However, since we are given the side length AC, we need to find the length of the other sides using the given angle B.

Finding the Length of the Other Sides

In a rhombus, opposite angles are equal. Therefore, if angle B is 60°, then angle A (opposite to B) is also 60°.

Using trigonometric functions, we can find the length of the other sides. The formula to find the length of the other sides in a rhombus is: Side Length = AC * cos(angle)

Substituting the given values: Side Length = 15.3 cm * cos(60°)

Calculating the Perimeter

Now that we have found the length of the other sides, we can calculate the perimeter using the formula: Perimeter = 4 * Side Length

Let's calculate the perimeter using the given values.

Result

The perimeter of the rhombus with angle B equal to 60° and side length AC equal to 15.3 cm is perimeter_value cm.
