Find RS.

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

RS =

Answer 1

Answer:

RS = 4.9

Step-by-step explanation:

Because the sides involved are hypotenuse and adjacent to the angle we use Cosine:

$\frac{RS}{7} = Cos(46)$

$RS = 7Cos(46)$

$RS = 4.86.....$

RS = 4.9

Answer 2

yo sup??

Again we have to apply trigonometry ie sine angle

sin46=QS/RS

sin46=sin45=√2 (for our convinience)

RS=7/√2

=4.9

Hope this helps.
