So,

Answer: The only difference between the six functions depends on the sides we use.
Step-by-step explanation:
The primary trigonometry ratio are
Sine (sin)
Cosine (cos)
Tangent (tan)
The reciprocal ratio are derived from the three primary functions. Because they can easily be derived, calculators and spreadsheets do not usually have them. These are:
Secant (sec)
Cosecant (csc)
Cotangent (cot)

Answer:
18 π cm^2.
Step-by-step explanation:
The area of the whole circle = π r^2 = 81π cm^2.
Since there are 360 degrees in a circle the area of the shaded region =
80/360 * area of the circle.
This = 80/360 * 81 π
= 2/9 * 81 π
= 18 π
Answer:
Corresponding side lengths and angle measures of two congruent triangles are also congruent.
Step-by-step explanation:
If two triangles ABC and DEF are congruent (see below figure) to each other then, AB=DE, BC=EF, AC=DF and <A=<D, <B=<E, <C=<F
