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}

If R is the midpoint of PS with PR = 7x + 23 and RS= 13x-19 then find PS
Rainbow [258]

If R is the midpoint of PS, then PR = RS -- (1)

Also, PR + RS = PS -- (2)

__________________

PR + RS = PS

7x + 23 + 13x - 19 = PS

__________________

Now, PR = PS

7x + 23 = 13x - 19

7x - 13x = -19 - 23

-6x = -42

x = -42/-6

x = 7

__________________

PS = 7x + 23 + 13x - 19

PS = 7(7) + 23 + 13(7) - 19

PS = 49 + 23 + 91 - 19

<u>PS </u><u>=</u><u> </u><u>1</u><u>4</u><u>4</u><u> </u>

Hope it helps!
