Final answer:
Trigonometric functions using the ratio of two sides can be used to solve right triangles.
Step-by-step explanation:
Trigonometric functions using the ratio of two sides of a triangle can be used to solve right triangles.
In a right triangle, the adjacent side is the side that is next to the angle being considered, and the opposite side is the side opposite to the angle. The hypotenuse is the side opposite the right angle.
The trigonometric functions sine, cosine, and tangent can be used to calculate the ratios of the sides of a right triangle.
For example, in a right triangle, the sine of an angle is equal to the ratio of the opposite side to the hypotenuse, the cosine is equal to the ratio of the adjacent side to the hypotenuse, and the tangent is equal to the ratio of the opposite side to the adjacent side.
These ratios can be used to solve for missing sides or angles in a right triangle.
