Finding the Lengths of AV and VS in Triangle ABC

To find the lengths of AV and VS in triangle ABC, we need to use the given information that angle A is 30 degrees and the length of AS is 12 cm.

Let's break down the problem step by step:

1. Determine the length of AV: - Since angle A is 30 degrees, we can use trigonometric ratios to find the length of AV. - In a right triangle, the sine of an angle is equal to the length of the side opposite the angle divided by the length of the hypotenuse. - In this case, AV is the side opposite angle A, and AS is the hypotenuse. - Therefore, we can use the sine function to find AV: AV = AS * sin(A).

2. Determine the length of VS: - To find the length of VS, we can use the Pythagorean theorem. - In a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides. - In this case, VS is one of the legs of the right triangle, and AV is the other leg. - Therefore, we can use the Pythagorean theorem to find VS: VS = sqrt(AS^2 - AV^2).

Let's calculate the values using the given information:

1. Length of AV: - AV = AS * sin(A) - AV = 12 cm * sin(30 degrees) - AV = 12 cm * 0.5 - AV = 6 cm.

2. Length of VS: - VS = sqrt(AS^2 - AV^2) - VS = sqrt((12 cm)^2 - (6 cm)^2) - VS = sqrt(144 cm^2 - 36 cm^2) - VS = sqrt(108 cm^2) - VS ≈ 10.39 cm.

Therefore, the length of AV is 6 cm and the length of VS is approximately 10.39 cm.

Please note that the calculations are based on the given information and assumptions about the triangle. If there are any additional constraints or details, please provide them for a more accurate answer.
