Question

Find the value of each trigonometric ratio. For example answer "2/3".

Answer 1

The value of sin X = 12 / 13

Explanation:

Given

• The angle ∠X

• The side opposite to angle ∠X = 12

• The hypotenuse = 13

To determine

sin X = ?

We know that the trigonometric ratio involving sin Ф such as

sin Ф = opposite / hypotenuse

Here:

• Ф = Angle X

• The side opposite of Angle X = 12

• Hypotenuse = 15

so substituting Ф = X, opposite = 12 and hypotenuse = 13 in the equation

sin Ф = opposite / hypotenuse

sin X = 12 / 13

Therefore, the value of sin X = 12 / 13
