HELP! USE EITHER LAW OF SINE OR LAW OF COSINE! HELP PLEASE! FIND THE MISSING SIDE AND MISSING ANGLES!

Answers

Answer 1

Answer:

∠Q ≈ 42.969, ∠P ≈ 52.03, QR ≈ 15.036

Step-by-step explanation:

Law of sines:

13/sin Q = 19/sin 85°

=> sin Q = 13 × sin 85°/19

=> Q = sin^-1 (13 × sin 85°/19)

=> Q ≈ 42.969

∠P=> 180 - 85 - 42.969 ≈ 52.03

QR/sin 52.03° = 19/sin 85°

=> QR = sin 52.03° × 19/sin 85°

=> QR ≈ 15.036

Answer 2

I hope this help with your math problem and more especially that you understand.

If A ( a , b ) and B ( b , a ) lie in 6x-y =1 and 2x - 5y = 5 respectively , find the equation of AB. Show your workings too!

~Thanks in advance! :D ​

Answers

Answer:

Solution given:

A(a,b) lie in 6x-y =1

substituting value of A in equation ,we get

6a-b=1...................(1)

B(b,a) lie in 2x - 5y = 5

substituting value of B in equation ,we get

2b-5a=5

b=5(a+1)/2............(2)

substituting value of b in equation 1 ,we get

6a-5(a+1)/2=1

12a-5a-5=2

7a=2+5

a=[tex] \frac{7}{7} [/tex]=1

substituting value of a in equation 1 ,we get

6×1-b=1

6-1=b

b=5

so points are A(1,5) and B(5,1)

we have

equation of line having two points

[tex](y - y1) = \frac{y2 - y1}{x2 - x1} (x - x1) [/tex]

[tex](y - 5) = \frac{1-5}{5-1} (x - 1) [/tex]

[tex](y - 5) = -1 (x - 1) [/tex]

y-5=1-x

x+y=6 is a required equation of line AB.

Sam and Dave, who are both Park Rangers, each manage a nature preserve. ​ ​Devin's nature reserve is 14 hectares and Sam's nature reserve is 14\cdot 10^{6}14⋅10 6 square meters. ​Who manages the smaller nature preserve? Note: 1 hectare = 10,000 square meters

Answers

Answer: Devin's

Step-by-step explanation:

Given

Devin's nature reserve is 14 hectares

Sam's nature reserve is [tex]14\times 10^6\ m^2[/tex]

Also, [tex]1\ \text{hectare}=10,000\ m^2[/tex]

Devin reserve in square meter [tex]14\ \text{hectares}=14\times 10^4\ m^2[/tex]

Clearly, [tex]14\times 10^6> 14\times 10^4[/tex]

So, Devin's manages smaller area

Answer:

176.25in^2

Step-by-step explanation:

You can tell that the two triangles on the left, and the two triangles on the right make a rectangle if you flip one of them. Because of this, you can multiply the base and height to get the area of both.

7.5*16=120 (left side)

7.5*7.5=56.25 (right side)

Now we add them to get the full area:

120+56.25=176.25in^2

a.When the numerator and the denominator have no common factor other than 1; he fraction is either a proper fraction or mixed number

Answers

Answer:

The fraction is a proper fraction (and irreducible)

Step-by-step explanation:

Given

[tex]x = Numerator[/tex]

[tex]y = Denominator[/tex]

[tex]Common\ factor = 1[/tex]

Required

The type of fraction

A fraction with the given features is a proper fraction and cannot be further reduced.

Take for instance:

[tex]x = 2[/tex]

[tex]y = 7[/tex]

The only common factor between [tex]2\ and\ 7[/tex] is 1

[tex]\frac{x}{y} = \frac{2}{7}[/tex]

See that 2/7 is a proper fraction and also 2/7 cannot be reduced (simplified)

The above logic is applicable to all fraction that have the attribute stated in the question (e.g. 3/7, 3/8, 4/9, 7/10, etc.)

A - 3/4 = 1/8 step by step explanation

Answers

Answer:

A-3/4=1/8 is the equation, if you expand 3/4 it is 6/8, in order to get 1/8 you need to subtract 6/8 from 7/8

7/8-6/8=1/8 therefor A=7/8

Determine whether the pair of coordinate pairs will make the linear inequality true or false.(10, 6).Y ≤ -5/5x+3

Answers

Answer:

False.

Step-by-step explanation:

We have the ordered pair (10, 6) and we want to see if this ordered pair is a solution of the inequality:

y  ≤ -5/5x+3

Remember that a generic ordered pair is written as (x, y)

Then for the ordered pair (10, 6) we have:

x = 10

y = 6

So we just need to replace these two values in the inequality and see if the inequality is true or false.

Replacing these values we get:

6  ≤ (-5/5*10) + 3

6  ≤ (-1/10) + 3

This is false, 6 is not less than the thing at the right, so we can conclude that (10, 6) is not a solution of the inequality.

So the coordinate pair makes the inequality false.
