Finding Two Different Solutions for an Angle of 30 Degrees

To find two different solutions for an angle of 30 degrees, we can use the properties of trigonometric functions. Specifically, we can use the sine, cosine, and tangent functions to calculate the values of the angle in different quadrants.

Solution 1: In the first solution, we will find the angle in the first quadrant, where both the sine and cosine functions are positive.

To find the angle in the first quadrant, we can use the sine function. 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, since we are given the angle, we can use the inverse sine function (also known as arcsine) to find the length of the side opposite the angle.

Let's denote the length of the side opposite the angle as 'x'. Using the inverse sine function, we can write the equation as:

sin(angle) = x/hypotenuse

Substituting the given angle of 30 degrees, we have:

sin(30) = x/hypotenuse

To find the value of 'x', we need to know the length of the hypotenuse. However, this information is not provided in the question. Therefore, we cannot determine the exact value of 'x' in this solution.

Solution 2: In the second solution, we will find the angle in the second quadrant, where the sine function is positive and the cosine function is negative.

To find the angle in the second quadrant, we can use the cosine function. The cosine of an angle is equal to the length of the side adjacent to the angle divided by the length of the hypotenuse. Again, since we are given the angle, we can use the inverse cosine function (also known as arccosine) to find the length of the side adjacent to the angle.

Let's denote the length of the side adjacent to the angle as 'y'. Using the inverse cosine function, we can write the equation as:

cos(angle) = y/hypotenuse

Substituting the given angle of 30 degrees, we have:

cos(30) = y/hypotenuse

To find the value of 'y', we need to know the length of the hypotenuse. However, this information is not provided in the question. Therefore, we cannot determine the exact value of 'y' in this solution.

In summary, we have found two different solutions for an angle of 30 degrees. However, without additional information about the lengths of the sides or the hypotenuse, we cannot determine the exact values of the sides in either solution.
