Answer:

x = 30

Step-by-step explanation:

Using the sine ratio in the right triangle

sinx = \frac{opposite}{hypotenuse} = \frac{2.5}{5} = \frac{1}{2} , then

x = sin^{-1} (\frac{1}{2} ) = 30

Answer:

  Either of ...

  • (x, y) ⇒ (-x, -y)

Step-by-step explanation:

There are at least two ways to express the transformation that maps each coordinate to its opposite.

  2. rotation 180° (either direction) about the origin.

Take your pick.

I have tried this like 10 diffrent ways<br> -3(r+9)=-32
KonstantinChe [14]
Distribute -3 to parenthasees
-3(r+9)=-3r-27

now we have
-3r-27=-32
add 27 to both sides
-3r+27-27=27-32
-3r+0=-5
-3r=-5
divide both sides by -3
r=-5/-3
r=5/3

−7m+4&lt;−45 <br><br> its an one-step problem help me please
aleksandr82 [10.1K]

Answer:

x > 7

Step-by-step explanation:

- 7m + 4 < - 45 ( subtract 4 from both sides )

- 7m < - 49

Divide both sides by - 7 , reversing the symbol as a result of dividing by a negative quantity.

m > 7
