What is the law of sines ?

he Law of Sines (or Sine Rule) is very useful for solving triangles.

According to the law ,

When we divide side a by the sine of angle A

it is equal to side b divided by the sine of angle B

and also equal to side c divided by the sine of angle C

[tex]\rm \dfrac{a}{sinA} = \dfrac{b}{sinB} = \dfrac{c}{sinC}[/tex]

It is given that in Δ PQR

r = 4.9 cm

angle R = 21

angle P =104

Length of p needs to be found

Therefore by using above equation

[tex]\rm \dfrac{r}{sinR} = \dfrac{p}{sinP}[/tex]

[tex]\rm \dfrac{4.9}{sin21^{0}} = \dfrac{p}{sin104^{0}}[/tex]

p= 13.3 cm

Therefore the length of p, to the nearest 10th of a centimeter is 13.3 cm .

What is the sum of the greatest and least numbers below:

Answers

Answer:

1/6

Step-by-step explanation:

Step 1: Make remaining mixed numbers improper fractions:

8 1/5 = ((8*5)+1)/5 = 41/5

-8 2/5 = -((8*5)+2)/5 = -42/5

Step 2: Order fractions from least to greatest:

-26/3 <- Least

-42/5

-54/7

41/5

53/6 <- Greatest

Step 3: Find the sum of the least and greatest fractions:

Given: -26/3+53/6

Make equivalent fractions: -52/6+53/6

Rearrange: 53/6-52/6

Evaluate: (53-52)/6 = 1/6

Therefore, the sum of the greatest and least numbers is 1/6

8.20= 8 1/5. -2 2/5= -8.4. -26/3= -8.6. -54/7=- 7.71. 53/6=8.8
53/6, 8 2/5 ,8 1/5, -54/7, -2 2/5, -26/3

solve system by elimination
6.
2x + 5y = 14
4x + 2 y = -4

Answers

Answer:

x=−3 and y=4

Step-by-step explanation:

Multiply the first equation by -2,and multiply the second equation by 1.

−2(2x+5y=14)

1(4x+2y=−4)

Becomes:

−4x−10y=−28

4x+2y=−4

Add these equations to eliminate x:

−8y=−32

Then solve−8y=−32for y:

−8y=−32

−8y

−8

=

−32

−8

(Divide both sides by -8)

y=4

Now that we've found y let's plug it back in to solve for x.

Write down an original equation:

2x+5y=14

Substitute4foryin2x+5y=14:

2x+(5)(4)=14

2x+20=14(Simplify both sides of the equation)

2x+20+−20=14+−20(Add -20 to both sides)

2x=−6

2x

2

=

−6

2

(Divide both sides by 2)

x=−3

Step by step:
Multiply the first one by -2 to be able to eliminate the x’s
-4x-10y=-28
Add them
-4x-10y=-28
4x+2y=-4
——————-
X’s cancel out your left with
-8y=-32
Divide by -8 to get y alone
Y= 4
Plug in for y to get x
4x+2(4)=-4
4x+8=-4
-8 -8
————-
4x=-12
x=-3
