Answer:

2 4/7

Step-by-step explanation:

3/7+4/7= 7/7 or 1 whole

So you add that to the 5 and get 6, then you need 2 to get to 8 because 6+2=8

Hope this helped!!!

Answer:

2 4/7

Step-by-step explanation:

let n = number to add to 5 3/7

change 5 3/7 to improper fraction: <u> 38 </u>

                                                            7

change 8 to become <u> 56 </u>

                                     7

create equation:

<u> 38 </u> + n = <u> 56 </u>

 7               7

n = <u> 56 </u> - <u> 38 </u>

       7        7

n = <u> 18 </u> or 2 4/7

       7

check:  5 <u> 3 </u> + 2 <u> 4 </u> = 8

                 7         7

5 + 2 = 7 and 3/7 + 4/7 = 1

7 + 1 = 8

Express the trigonometric ratios sinA in term of cosA​
MariettaO [177]

Answer:

sinA = ± \sqrt{1-cos^2A}

Step-by-step explanation:

Using the Pythagorean identity

sin²A + cos²A = 1 ( subtract cos²A from both sides )

sin²A = 1 - cos²A ( take the square root of both sides )

sinA = ± \sqrt{1-cos^2A}
