In a 30-60-90 triangle, the length of the side opposite the 30 degree angle is 8. Find the length of the side opposite the 60 de
nalin [4]

Answer:

The length of the side opposite the 60 degree angle 'c' = 4

Step-by-step explanation:

<u>Step(i)</u>:-

Given data ∠A = 90° , ∠B = 60° and ∠C = 30°

Given data the length of the side opposite the 30 degree angle is 8

let  'a' = 8

<u><em>step(ii)</em></u>:-

<em>By using sine rule formula in properties of triangle</em>

<em></em>\frac{a}{Sin A} = \frac{b}{Sin B} = \frac{c}{Sin C} = 2 R<em></em>

<em></em>\frac{a}{Sin A}  = \frac{c}{Sin C}<em></em>

\frac{8}{Sin 90}  = \frac{c}{Sin 30}

cross multiplication , we get

\frac{8 X sin 30}{Sin 90}  = c<em></em>

<em>we know that trigonometry formulas</em>

<em>sin 30° = </em>\frac{1}{2}<em>   and sin 90°= 1</em>

<em>C =  8 X 1/2 = 4</em>

<u><em>conclusion</em></u>:-

<em>The length of the side opposite the 60 degree angle 'c' = 4</em>

<em></em>

Simplify fully<br> 6x2 +x–1 4x2 – 1
AlexFokin [52]

Answer:

​3x−1

Step-by-step explanation:

1 Split the second term in 6{x}^{2}+x-16x

​2

​​ +x−1 into two terms.

\frac{6{x}^{2}+3x-2x-1}{4{x}^{2}-1}

​4x

​2

​​ −1

​

​6x

​2

​​ +3x−2x−1

​​  

2 Factor out common terms in the first two terms, then in the last two terms.

\frac{3x(2x+1)-(2x+1)}{4{x}^{2}-1}

​4x

​2

​​ −1

​

​3x(2x+1)−(2x+1)

​​  

3 Factor out the common term 2x+12x+1.

\frac{(2x+1)(3x-1)}{4{x}^{2}-1}

​4x

​2

​​ −1

​

​(2x+1)(3x−1)

​​  

4 Rewrite 4{x}^{2}-14x

​2

​​ −1 in the form {a}^{2}-{b}^{2}a

​2

​​ −b

​2

​​ , where a=2xa=2x and b=1b=1.

\frac{(2x+1)(3x-1)}{{(2x)}^{2}-{1}^{2}}

​(2x)

​2

​​ −1

​2

​​  

​

​(2x+1)(3x−1)

​​  

5 Use Difference of Squares: {a}^{2}-{b}^{2}=(a+b)(a-b)a

​2

​​ −b

​2

​​ =(a+b)(a−b).

\frac{(2x+1)(3x-1)}{(2x+1)(2x-1)}

​(2x+1)(2x−1)

​

​(2x+1)(3x−1)

​​  

6 Cancel 2x+12x+1.

\frac{3x-1}{2x-1}

​2x−1

​

​3x−1

 Julian is making barbecue sauce to can. He uses 15 cups of tomato sauce, 6 cups of white vinegar, cup of honey, and cup of map
Advocard [28]
STEP 1:
Add up all cups of ingredients

=15 + 6 + 1 + 1
= 23 cups of ingredients


STEP 2:
convert cups to quarts
4 cups= 1 quart

=23 ÷ 4
divide total cups by # of cups in 1 quart

= 5 quarts (with 3 cups left)


STEP 3:
find number of pints with 3 cups left
2 cups= 1 pint

= 3 ÷ 2
divide total cups left by # cups in 1 pint

= 1.5 pints

*Add the number of pints in step 3 to the number of quarts in step 2.


ANSWER: He can fill 5 quarts and 1.5 pints.

Hope this helps! :)
