Find RS.

Write your answer as an integer or as a decimal rounded to the nearest tenth.


RS =

Answer 1

The measurement of Rs is 3.9

Step-by-step explanation:

We can see that the given triangle is a right triangle where according to Angle S, Base is RS and Hypotenuse is SQ

SQ = 8

We have to use any trigonometric ratio to find the length of RS

As RS is the base, we will use cosine

so,

$cos\ 61 = \frac{RS}{QS}\\0.4848 = \frac{RS}{8}\\8 * 0.4848 = RS\\RS = 3.8784$

Rounding off to nearest tenth

$RS = 3.9$

Hence,

The measurement of Rs is 3.9
