Answer: x is less than or equal to -4.25

Step-by-step explanation:

Since the dot on the number line is filled in it is either a less than or equal to or a greater than or equal to. Because the line is going more into negative or descending, it is less than or equal to.

Find an exact value. Cos 75° negative square root of six plus square root of two quantity square root of six minus square root o

ehidna [41]

Answer:

√2(√3 - 1)/4

Step-by-step explanation:

To find an exact value for Cos75°, we use the compound angle formula. Since 75° = 45° + 30°, Cos75° = Cos(45° + 30°).

Using Cos(A + B) = CosACosB - SinASinB where A = 45° and B = 30°,

Cos75° = Cos(45° + 30°) = Cos45°Cos30° - Sin45°Sin30°

Now Cos45° = Sin45° = 1/√2 = √2/2, Cos30° = √3/2 and Sin30° = 1/2.

Substituting these values into the above equation, we have

Cos75° = Cos(45° + 30°)

= Cos45°Cos30° - Sin45°Sin30°

= √2/2 × √3/2 - √2/2 × 1/2

= √6/4 -√2/4

= √2(√3 - 1)/4

The angles in a triangle are in the ratio 1:2:3. Show that this triangle is a right-angled triangle. The hypotenuse of the trian

natita [175]

Answer:

see explanation

Step-by-step explanation:

(a)

Sum the parts of the ratio , 1 + 2 + 3 = 6 parts

Divide sum of angles in a triangle by 6 to find the value of one part of the ratio.

180° ÷ 6 = 30° ← value of 1 part of the ratio

2 parts = 2 × 30° = 60°

3 parts = 3 × 30° = 90°

Since there is an angle of 90° then the triangle is right.

(b)

The shortest side is the side opposite the smallest angle of 30°

Using the sine ratio and the exact value

sin30° = $\frac{1}{2}$ , then

sin30° = $\frac{opp}{hyp}$ = $\frac{opp}{19}$ = $\frac{1}{2}$ ( cross- multiply )

2 opp = 19 ( divide both sides by 2 )

opp = 9,5

Shortest side in the triangle is 9.5 cm

3(1 – 2x) > 3 – 6х help

coldgirl [10]

Answer:

<h2> $\huge \: x \in ∅$ </h2>

Step-by-step explanation:

<h3>to understand this</h3><h3>you need to know about:</h3>

inequality
distribution
PEMDAS

<h3>given:</h3>

$3(1 - 2x) > 3 - 6x$

<h3>to solve:</h3>

$x$

<h3>let's solve:</h3>

$step - 1 : define\\ 3(1 - 2x) > 3 - 6x$

$step - 2: distribute\\ 3 - 6x > 3 - 6x$

$step - 3 : \\ add \: 6x \: to \: both \: sides$

$3 - 6x + 6x> 3 - 6x + 6x$

$3 > 3$

$\therefore \: the \: statement \: is \: false \: for \: any \: value \: of \: x \: because \: both \: sides \: are \: identical$

therefore,

$x \in ∅$
