Answer:

I hope this helps

Step-by-step explanation:

This is not the same exact question but it shows you the throw down.

A+B+C= 180

so if A=60 and B=70

The sin is= 8

so 60+70= 130

130+c=180

130-180= 50

Please help me. I am having some trouble with these problems
s344n2d4d5 [400]

Answer:

Step-by-step explanation:

This is a proportion problem. I think you just lost a zero.

12/100 = 9/x                    Cross multiply

12x = 100*9                      Combine the right.

12x = 900                         Divide by 12

12x/12 = 900/12

x = 75 grams

So if you put 75 grams of tasty Oats in a bowl and covered it with milk the cereal would give you 9 grams of Protein.

2.

1 gram of Tasty Oats cereal contains 12/100 = 0.12 grams of protein.

1 gram of Cornbits contains 5/45 = 0.11 grams of protein.

By the narrowest of margins the Tasty Oats has more protein in it.

The angles 3x+6 and 5x + 6 are supplements. What are the two angles
yarga [219]

Answer:

x = 21

Step-by-step explanation:

<u>Step 1:  Make an expression</u>

Since they are supplements, that means that they add up to 180 degrees.

3x + 6 + 5x + 6 = 180

<u>Step 2:  Combine like terms</u>

3x + 6 + 5x + 6 = 180

(3x + 5x) + (6 + 6) = 180

8x + 12 = 180

<u>Step 3:  Subtract 12 from both sides</u>

8x + 12 - 12 = 180 - 12

8x = 168

<u>Step 4:  Divide both sides by 8</u>

8x / 8 = 168 / 8

x = 21

Answer:  x = 21
