Verify sin(180-theta)=sin(theta) (SHOW WORK)

Kobotan [32]

Answer:

see the explanation

Step-by-step explanation:

we know that

$sin(A-B)= sinAcosB-cosAsinB$

we have

$A=180\°\\ B=\theta$

$sin(180\°-\theta)= sin(180\°)cos(\theta)-cos(180\°)sin(\theta)$

Remember that

$sin(180\°)=0$

$cos(180\°)=-1$

substitute

$sin(180\°-\theta)= (0)cos(\theta)-(-1)sin(\theta)$

$sin(180\°-\theta)=sin(\theta)$ ----> is verified

Determine whether the ordered pair is a solution to the system:

scZoUnD [109]

Answer:

Step-by-step explanation:

5x-2y=24

5x=24+2y____equ 1

2x+y=6

Y=6-2x______equ 2

Now substitute the value of y in equation 1

5x=24+2y

5x=24+2(6-2x)

5x=24+12-4x

5x+4x=36

X=36/9

X=4

Now, put the value of x in equation 2

Y=6-2x

Y=6-2*4

Y= -2

(4,-2)

Pepsi [2]

Answer:

78 persons

Step-by-step explanation:

Given

$Budget = 3000$

$Clean\ up = 100$

$Rate = 37\ per\ person$

Required

Determine the maximum number of person that can be invited

Let the number of persons be p.

If the hall charges $37 for 1 person, then it will charge $37p for p persons.

So:

$Charges = 37p$

The expression becomes:

$Clean\ up + Charges = Budget$

Substitute values for Clean up, Charges and Budget

$100 + 37p = 3000$

Subtract 100 from both sides

$100 - 100 + 37p = 3000 - 100$

$37p = 3000 - 100$

$37p = 2900$

Make p the subject

$p = \frac{2900}{37}$

$p = 78.378$

Round down

$p = 78$

Hence, they can only invite 78 people to stay within budget

Elodia [21]

Answer:

EG is 19 units

Step-by-step explanation:

Let us solve the question

∵ Lines CD and EF intersected at point G

∴ CD = CG + GD

∴ EF = EG + GF

∵ Line EF bisects line CD

→ That means G is the midpoint of CD

∴ CG = GD

∵ CG = 5x -1

∵ GD = 7x - 13

→ Equate them to find x

∴ 7x - 13 = 5x -1

→ Add 13 to both sides

∴ 7x -13 + 13 = 5x - 1 + 13

∴ 7x = 5x + 12

→ Subtract 5x from both sides

∴ 7x - 5x = 5x - 5x + 12

∴ 2x = 12

→ Divide both sides by 2

∴ $\frac{2x}{2}=\frac{12}{2}$

∴ x = 6

∵ EF = 6x - 4

→ Substitute x by 6 to find its length

∴ EF = 6(6) - 4 = 36 - 4

∴ EF = 32

∵ EF = EG + GF

∵ GF = 13

∴ 32 = EG + 13

→ Subtract 13 from both sides

∵ 32 - 13 = EG + 13 - 13

∴ 19 = EG

∴ EG = 19 units
