Answer 1

Answer:

C)    $\frac{5}{13}$

Step-by-step explanation:

This question requires trigonometry. Trigonometry is used to work out lengths or angles when you are already given some. In this question we are given which formula to use but I will tell how to figure it out if the question doesn't give it to you. The formula's are

Sin⁻¹ = Opposite ÷ Hypotenuse

Tan⁻¹ = Opposite ÷ Adjacent

Cos⁻¹ = Adjacent ÷ Hypotenuse

First of all we have to label the sides,

→ The hypotenuse is the angle opposite the right angle so it is 13

→ The opposite is the side opposite the angle so it is 5

→ The adjacent is the remaining side so it is 12

In the question it has given us the formula to use so we use it,

→ Sin⁻¹ = Opposite ÷ Hypotenuse

⇒ Substitute in the values

→ Sin⁻¹ = 5 ÷ 13

The value of sinM is    $\frac{5}{13}$
