Question

Solve for each variable.

   

x ≈ 4.56, y ≈ 2.04

   

x ≈ 14.62, y ≈ 5.32

   

x ≈ 4.70, y ≈ 1.71

   

x ≈ 1.71, y ≈ 4.70

The image shows a right triangle with the following details:

- The hypotenuse is labeled as 5 units.
- One angle is labeled as 20°.
- The side opposite the 20° angle is labeled as \( x \).
- The side adjacent to the 20° angle is labeled as \( y \).
- The triangle includes a right angle, indicated by the small square at the junction of sides \( x \) and \( y \).

This diagram can be used to explore trigonometric relationships in right triangles, particularly with the sine, cosine, and tangent functions relative to the 20° angle.
