Answer:

(D) 0.36

Explanation:

Given: It is given that in ΔABC, which is right angled at A has AC=13, AB=5 and BC=13.93.

To find: The value of sinC.

Solution: It is given that in ΔABC, which is right angled at A has AC=13, AB=5 and BC=13.93. thus, using the trigonometry that is:


sinC=(Perpendicular)/(Hypotenuse)


sinC=(AB)/(BC)

Substituting the given values, we have


sinC=(5)/(13.93)


sinC=0.36

which is the required value.

Hence, option D is correct.

Answer

Find the approximate value of sin C .

To proof

By using the trignometric identity


sin\theta = (Perpendicular)/(Hypotenuse)

Now as given in the diagram


sin C = (AB)/(BC)

as in the diagram

AB = 5 units

BC = 13.93 units

Now put it in the identity


sinC = (5)/(13.93)

solving

sinC = 0.36° (approx)

Option (D) is correct

Hence proved
