Find the value of cos G rounded to the nearest hundredth.
Amiraneli [1.4K]

Answer:

\sf \cos(G)=\dfrac{1}{2}

Step-by-step explanation:

<u>Trigonometric ratios</u>

\sf \sin(\theta)=\dfrac{O}{H}\quad\cos(\theta)=\dfrac{A}{H}\quad\tan(\theta)=\dfrac{O}{A}

where:

  • \theta is the angle
  • O is the side opposite the angle
  • A is the side adjacent the angle
  • H is the hypotenuse (the side opposite the right angle)

Given:

  • \theta = G
  • A = GF = 2
  • H = EG = 4

\implies \sf \cos(G)=\dfrac{2}{4}=\dfrac{1}{2}

Which ordered pair is the solution to this system of equations?<br> y=2x-3 <br> y=7-0.5x
disa [49]

Answer:

(4, 5)

Step-by-step explanation:

y = 2x - 3

y = 7 - 0.5x

y is already isolated on both equations, set them equal to each other:

2x - 3 = 7 - 0.5x

add 3 to both sides:

2x = 10 - 0.5x

add 0.5x to both sides:

2.5x = 10

divide by 2.5:

x = 4

plug in 4 for x on either equation and solve for y:

y = 2(4) - 3

y = 8 - 3

y = 5

(4, 5)
