Answer 2

Given Information:

In triangle ASD, the following information is known: - Angle ADS = 106 degrees - Angle A = Angle S = 53 degrees - DR is the height of the triangle - DR = 39 cm

Solution:

To find the length of side AS, we can use the trigonometric ratios in a right triangle. Since we know the height DR and the angles, we can use the tangent function.

The tangent of an angle is defined as the ratio of the length of the opposite side to the length of the adjacent side. In this case, the opposite side is DR and the adjacent side is AS.

Using the tangent function, we can write the equation:

tan(A) = DR / AS

Substituting the given values:

tan(53) = 39 / AS

To find the value of AS, we can rearrange the equation:

AS = 39 / tan(53)

Now, we can calculate the value of AS using a calculator:

AS ≈ 39 / tan(53) ≈ 39 / 1.327044821 ≈ 29.41 cm

Therefore, the length of side AS is approximately 29.41 cm.

I hope this helps! Let me know if you have any further questions.
