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}

Line k has a slope of - 1/6. What is the slope of a line that is perpendicular to like k?
Lemur [1.5K]
The slope of a line and the perpendiular line that intercept will always have a product of -1

If the slope k=-1/6, the perperndicular line can be found by finding the product of the slope and -1

-1= (slope)(perpendicular line slope)
perpendicular line slope= slope(-1)
                             = -1/6(-1)
                             = 6
