Answer: 80 degrees

Step-by-step explanation:

Answer:

B = 54 to the nearest degree.

Step-by-step explanation:

Remark

This is a sine law question. They can be rather nasty because no answer or 2 answers are possible. This one is well behaved because B, you are told, is acute. The two answer kind needs the supplement of an acute angle.

Sorry this blabs on and shouldn't. You are looking for <B

Formula

Sin(<B)/the side opposite = Sin(<A) / side opposite it

Simplified

Sin(<B) / 9 = Sin(A)/11

Sin(<B) / 9 = Sin(80) / 11             Multiply both sides by 9

9*Sin(B) / 9 = 9 * Sin(80) /11      The 9s Cancel

Now all you need to do is put it in your calculator. Do you need the steps?

Sin(B) = 9*sin(80) / 11

Sin(B) = 9 * 0.9848 /11

Sin(B)= 0.8058

B = Sin-1(0.8058)

B = 53.68

B = 54

Answer:

7 - (-3)

Step-by-step explanation:

7 + 3 = 7 - (-3).

Answer:

9

Step-by-step explanation:

So the little arrows on the lines means they are equal to each other so if you look, A to D and B to C have only one arrow meaning those two lines are the same lines

and A to B and D to C have two arrows meaning those two lines are the same

so that means if A to B is 9 and it's equal to the line D to C, then D to C is also 9

Hopefully this wasn't too confusing

Answer:

mCD = 9

Step-by-step explanation:

Because this polygon has opposite parallel sides, meaning each side across from each other are parallel, we know that this is a parallelogram. So:

AB ║ DC

BC ║ AD

Because this is a parallelogram, we know that, from the properties parallelograms, opposite sides of a parallelogram are congruent. This means that AB ≅ DC.

This also means that because AB = 9 and AB = DC, DC = 9.

Here's a mini two-column proof:

Statements     →     Reasons

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

mAB = 9     →     Given

AB ║ DC, BC ║ AD      →     Given

ABCD is a parallelogram      →     Definition of a Parallelogram

AB ≅ DC      →     Opposite sides of a parallelogram are congruent.

mAB = mDC      →     Definition of Congruent Segments

9 = mDC      →     Substitution Property of Equality

mCD = mDC      →     Reflexive Property of Equality

mCD = 9     →     Substitution Property of Equality

Answer:

y > 81

Step-by-step explanation:

82 - 28 = 54

So, 54 > 53

Answer:

B.11 correct

Step-by-step explanation:

a=5

a+6

5+6=11

11 is the correct answer so B.11 is correct

Answer:

11

Step-by-step explanation:

If a=5 and there is a+6 you need to plug in the 5 from the a=5 in the equation a+6 to get 5+6 which equals 11 :D

Answer:

x = 18

Step-by-step explanation:

[tex]\frac{8}{12} = \frac{12}{x}[/tex]

8x = 12 * 12

8x = 144

[tex]\frac{8x}{8} = \frac{144}{8}[/tex]

x = 18

Answer:

5.2

Step-by-step explanation:

a^2+b^2=c^2

a^2+3^2=6^2

a^2+9=36

-9. -9

-----------------

square root a^2 = square root 27

a= 5.1961524227

a = 5.2

Answer:

-6

Step-by-step explanation:

if they were both positive numbers, it would be 6. But when you multiply a negative by a positive, the answer is negative.

Answer:

-6

Step-by-step explanation:

When you multiply a positive number by another positive number, you will always get a positive number as your answer. Same thing for negative. If you multiply a negative by a negative, you will always get a positive. However, when you multiply a negative by a positive, you will always get a negative number.

Since you know this, you can multiply 2 by 3, which is 6. Because 2 is negative and 3 is positive, you know that the answer must be negative. Therefore, you add the negative symbol to 6, giving you -6.

I hope this isn't too confusing. Please let me know if you have any more questions. Good luck!

Answer:

A) $2.34

B) $17.94

Step-by-step explanation:

First in order to find the tip you need to set up a proportion:

15/100 = x/15.6

Step 1: Cross-multiply.

15/100 = x/15.6

(15)*(15.6) = x*(100)

234 = 100x

Step 2: Flip the equation.

100x=234

Step 3: Divide both sides by 100.

100x/100 = 234/100

x = 117/50 (2.34)

The tip is $2.34

Now to find the total, add the tip to the bill.

15.6+2.34

= 17.94

The total bill was $17.94

Answer:

3 4/5

Step-by-step explanation:

7 3/10 - 3 9/10=

In this case 3/10 - 9/10 is cannot  be so we have to borrow 1 whole from 7

so, 7 3/10 will become 7 3/10 + 1 or to add we have to change 1 as 10/10, any way 1 and 10/10 is equal but in this case we will use 10/10 to add 1 whole to 3/10 and minus 1 whole to 7

so, 3/10 + 10/10 = 13/10

and 7 - 1 = 6

so, 7 3/10 as 6 13/10

any way 7 3/10 and 6 13/10 is equal but, in this case we have to use 6 13/10 to minus, because 7 3/10 is cannot be

so, 6 13/10 - 3 9/10 =

=3 4/10 or 3 2/5
