According to above diagram :

RT = RS + ST

that is :

now, RT = 2x + 75

hence , RT = 31 units

Answer:

RT = 31

Solve for x:

[tex]x=-22[/tex]

Step-by-step explanation:

==>> The sum of the line is RST

[tex]4x+107+12=RST[/tex]

==>> Since [tex]RST = 2x + 75[/tex], the equation will newly become [tex]4x+107+12=2x+75[/tex]

--

To find [tex]4x+107[/tex], we need to find the x.

==>> [tex]x=-22[/tex]

-- Lets check our work

==>> [tex]4(-22) = -88[/tex]

[tex]-88 + 107 = 19 [RS = 19][/tex]

[tex]RS + ST = 19 + 12 =[/tex] 31

--

[tex]2(-22) = -44[/tex]

[tex]-44 + 75 =[/tex] 31

31 = 31

Answer:

Step-by-step explanation:

substituting in the values of s, b,t and n in the expression then,

(2.4 × -7.2 × 4.8) - (-7.2 × 4.8 × -9.6)

= - 82.944 -331.776

= -248.832

Answer:

Step-by-step explanation:

9x -1 +5x -15 = 180 supplementary angles

14x = 196

x = 14 sub into

5x -15= y -20 opposite angles

5(14) -15+20 =y

75 = y.

Answer: - 4d

Step-by-step explanation:

In the equation, there's an invisible 1 in front of the first d, so let's add that.

1d - 2d - 3d

Since all the terms in the above equations are like terms, we would focus on only subtracting. We would first subtract 2d from 1d.

- 1d - 3d

We then subtract 3d from - 1d. This would give us our answer.

- 4d

The measure of m<QRX and m<QRP are 129 and 51 degrees respectively.

The sum of the interior angle of a triangle is 180 degrees, hence;

m<QPR + m<QRP + M<PQR = 180

Substitute the given parameters

49 + m<QRP + 80 = 180

m<QRP + 129 = 180

m<QRP = 180 - 129

m<QRP = 51 degrees

The sum of interior angle is equal to the exterior

m<QPR +  M<PQR = m<QRX

m<QRX = 49 + 80

m<QRX = 129 degrees

Hence the measure of m<QRX and m<QRP are 129 and 51 degrees respectively.

Answer:

The length of the model is 6 inches.

Step-by-step explanation:

The wingspan of the airplane and length of the airplane are a ratio of 4:3

The model is also supposed to be 4:3.

4:3 x 2 = 8:6

Or, 20x12=240

240/8=30

15x12=180

180/30=6.

Answer:

6 inches

Step-by-step explanation:

Answer:

x=6

Step-by-step explanation:

Step 1:

Subtract 3x from both sides:

4x + 8 - 3x = 3x + 14 - 3x

x + 8 = 14

Step 2:

Subtract 8 from both sides:

x + 8 - 8 = 14 - 8

x = 6

Step-by-step explanation:

The relevant trig relations are summarized by the mnemonic SOH CAH TOA. This means ...

  Sin = Opposite/Hypotenuse

  Cos = Adjacent/Hypotenuse

  Tan = Opposite/Adjacent

So, for each triangle, determine the relationships of the given sides to the given angle: adjacent, opposite, or hypotenuse. Then write and solve the equation using one of the above templates.

Answer:

x = 32

<1 = 102 degrees

<2 = 78 degrees

Step-by-step explanation:

3x + 6 + 2x + 14 = 180

5x + 20 = 180

5x = 180 - 20

x = 160/5

x = 32

3(32) + 6 = 102 degrees

180 - 102 = 78 degrees
