Question

what type of triangles do you use the trig ratios with? right triangle acute triangle any type obtuse triangle

Explanation:

Trigonometric ratios (sine, cosine, tangent) are defined based on the sides of a right - triangle. For example, in a right - triangle with hypotenuse \(c\), adjacent side \(a\) to an angle \(\theta\), and opposite side \(b\) to the angle \(\theta\), \(\sin\theta=\frac{b}{c}\), \(\cos\theta = \frac{a}{c}\), \(\tan\theta=\frac{b}{a}\). These definitions rely on the right - angle of the triangle. While trigonometric concepts can be extended to non - right triangles (using the law of sines and law of cosines), the basic trigonometric ratios (as initially learned) are for right - triangles.

Answer:

right triangle
