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

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.

Write the equation in standard form 3x + 1 = 2y
yulyashka [42]
The standard form of an equation is
ax + by = c

In the question, we have the following formula
3x + 1 = 2y

To get the formula in standard form, we first have to subtract 2y from both sides (since we need to get 2y on the left side)
3x - 2y + 1 = 0

Finally we subtract 1 from both sides (since we need the number on the right side)
3x - 2y = - 1

Hence, 4. is the correct answer.

If 86 is added to a number the result is 56 less than twice the number, find the exact number, Do not round!
vredina [299]
The number is 142
you first make an equation ;
86+x=2x-56
Add 56 to both sides
142+x=2x
Subtract x from both sides
142=x
