1. By definition, you have:
Sin(α)=Opposite/Hypotenuse
2. Then, SinA is:
SinA=BC/AC
A is the angle in the vertice "A".
BC is the opposite leg to the the angle A.
AC is the hypotenuse of the triangle.
3. By definition, you have:
Cosα=Adjacent/Hypotenuse
4. Then, CosC is:
CosC=BC/AC
C is the angle at the vertice "C".
BC is the adjacent leg to the angle C.
AC is the hypotenuse.
5. Therefore, the answer is the last option:
The equivalent to SinA is CosC
Answer:
Vales of a =3 and b = 6
Step-by-step explanation:
Given that: 
.....[1] where a and b are positive integers
we can write 81 and 24 as;
We have [1] as;
Using power rules;
which implies a = b
then;
On comparing both sides we have;
a = 3 and
⇒
Therefore, the value of a and b are, 3 and 6
