8-2.5 is 5.5 because when you subtract 2 from 6 you get 6b and when you subtract .5 from 6 you get 5.5

Fill in the blank. In the triangle below, y=
arsen [322]

Answer:

47.10

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you that ...

... Cos = Adjacent/Hypotenuse

The value y is the length of the hypotenuse, and the given length 35 is the side adjacent to the given angle. Thus, the cosine relationship will be helpful.

Filling in the given values, we have ...

... cos(42°) = 35/y

Multiplying by y/cos(42°), we can find y to be ...

... y = 35/cos(42°) ≈ 35/0.7431

... y ≈ 47.10

Y will be approximately  47.10 in length

Step-by-step explanation:

we will use this  form that we memorized in our schools ............. SOH CAH TOA

CAH means , Cos ∅= Adjacent/Hypotenuse

Given values

∅ =42°

hypotenuse= y

adjacent side length = 35

now putting in our values  into

Cos ∅= Adjacent/Hypotenuse

OR

cos(42°) = 35/y

by multiplying y on both sides we get

y= 35/cos( 42°)

cos(42°)= 0.743

so  y= 35/0.743    

y = 47.10632

OR

y ≈ 47.10

Find g.<br> Write your answer as an integer or as a decimal rounded to the nearest tenth.
Soloha48 [4]

Step-by-step explanation:

\frac{EG}{  \sin(/EFG)  } =   \frac{EF}{ \sin(/EFG) }  \\  \frac{7}{ \sin(36°) }  =  \frac{g}{ \sin(121°) }  \\ g = 10.208

Help with this math question please
Masja [62]
| -6x - 3 | > 15

This expression can be written as:

a) -6x - 3 > 15 
b) -15 > - 6x - 3

Solving a part:

- 6x - 3 \ \textgreater \  15 \\  \\ &#10;- 6x \ \textgreater \  18 \\  \\ &#10;x \ \textless \  -3

Solving b part:

-15 \ \textgreater \  - 6x - 3 \\  \\ &#10;-12 \ \textgreater \  - 6x \\  \\ &#10;2 \ \textless \  x

or we can write:
x > 2

So the solution to given inequality is:
x \ \textless \  -3  \\ or  \\ x \ \textgreater \  2

The second option correctly lists this solution.
