<u>Answer</u>:

least to greatest: ∠I < ∠J < ∠H

<u>Explanation</u>:

<u>angle I: </u>

cosI = \frac{10^2+12^2-8^2}{2*10*12}

I = cos^{-1} (\frac{3}{4} )

I = 41.41°

<u>angle H:</u>

cosH = \frac{10^2+8^2-12^2}{2*10*8}

H = cos^{-1} (\frac{1}{8} )

H = 82.82°

<u>angle J:</u>

cosJ = \frac{8^2+12^2-10^2}{2*8*12}

J = cos^{-1}(\frac{9}{16} )

J = 55.77°

<em>They sum up to 180°, so the steps are correct.</em>

Mark the theorem below

  • The angle which measures biggest the opposite side of that angle is biggest.

Here

  • 8<10<12
  • JH<IH<JI

Now

  • <I < <J < <H

15. Find the value of x and y rounded to the nearest tenth.<br> X<br> 34<br> 45°<br> 30°<br> y
Ugo [173]

Answer:

x = 24.0

y = 46.4

Step-by-step explanation:

Let opposite side = z

Using trigonometry :

Sin 30 = z / 34

z = 0.5 * 34

z = 17

We find x :

Sin 45 = 17 / x

x * sin45 = 17

x = 17 / sin 45

x = 24.04

Let y = y1 + y2

y1 = 17 / tan45

y1 = 17

y2 = 17/tan30

y2 = 29.44

y = 17 + 29.44

y = 46.44

ladessa [460]
Let O be the amount of orange juice and W be the amount of water.

A)
O = 0.8W

B)
W = 1, so:
O = 0.8(1)
O = 0.8 Liters

If you are at (0,0) on a coordinate grid, what direction do you go to plot point (-2,6)​
lidiya [134]

Answer:

go left 2 and up 6

Step-by-step explanation:

(x,y)

(x,y) --> (-2,6)

0 = x      0 = y

0 - 2 = -2 = x

0 + 6 = 6 = y

(-2,6)

When making the X negative, you want to go left on the grid. When making Y positive, you want to go up on the grid.

FIRST PERSON TO ANSWER GETS BRANILYEST
Veseljchak [2.6K]

Car A                               Car B

d=rt                                  d = rt

d = ra * 2.4                        d = rb 4

ra = rb+22

distances are the same so set the equations equal

ra * 2.4 =rb *4

substitue in  for ra

(rb+22) 2.4 =rb *4

distribute

2.4 rb +52.8 = 4 rb

subtract 2.4 rb from each side

52.8 = 1.6 rb

33 = rb

Car b travels at 33 miles per hour

Car a = 33+22

Car a = 55 miles per hour
