Answer:

x = 20.41 units, y = 11.71 units to the nearest hundredth.

Step-by-step explanation:

Consider the small triangle:

cos 20 = 11/y

y = 11 / cos 20

= 11.706 units.

Now the larger triangle:

sin 35 = 11.706 / x

x = 11.706 / sin 35

x = 20.409 units.

Answer:

x ≈ 20.42, y ≈ 11.71

Step-by-step explanation:

Using the cosine ratio on the right triangle on the right, that is

cos20° = \frac{adjacent}{hypotenuse} = \frac{11}{y}

Multiply both sides by y

y × cos20° = 11 ( divide both sides by cos20° )

y = \frac{11}{cos20} ≈ 11.71

Using the sine ratio on the right triangle on the left, that is

sin35° = \frac{opposite}{hypotenuse} = \frac{y}{x} = \frac{11.71}{x}

Multiply both sides by x

x × sin35° = 11.71 ( divide both sides by sin35° )

x = \frac{11.71}{sin35} ≈ 20.42

Use the elimination method to solve the system of equations. Choose the correct ordered pair<br>​
UkoKoshka [18]

Answer:

Answer is B

Step-by-step explanation:

12x - y = 25 \\ 9x + y = 17 \\ x =  \frac{17 - y}{9}  \\ 12( \frac{17 - y}{9} ) - y = 25 \\

\frac{204}{9}  -  \frac{12}{9} y - y = 25 \\  \frac{204}{9}  -  \frac{21y}{9}  = 25 \\  -  \frac{21y}{9}  = 25 -  \frac{204}{9}  \\  -  \frac{21y}{9} =  2.33 \\ - 21y =  20.997 \\ y =  - 0.99

y =  - 1 \\ x =  \frac{17 - y}{9}  \\ x =  \frac{17 -  - 1}{9}  =  \frac{18}{9}   \\ x = 2
