Andreyy89

Answer:

A = 125º

Step-by-step explanation:

Missing angle is the supplement of 157.5

180 - 157.5 = 22.5

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

Sum of angles in triangle is 180

22.5 + (-10x) + (-x + 20) = 180

Combine like terms

-11x + 42.5 = 180

Subtract 42.5 from both sides

-11x = 137.5

Divide both sides by -11

x = -12.5

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

A = -10(-12.5)

A = 125º

Answer:

$Center = \boxed{1}, \: \boxed{ - 2} \: ; \: Radius = \boxed{3}$

Step-by-step explanation:

${x}^{2} + {y}^{2} - 2x + 4y - 4 = 0 \\ \\ ({x}^{2} - 2x + 1 - 1) + ( {y}^{2} + 4y + 4 - 4) - 4 = 0 \\ \\ ( {x}^{2} - 2x + 1) + ( {y}^{2} + 4y + 4) - 9 = 0 \\ \\ {(x - 1)}^{2} + {(y + 2)}^{2} = 9 \\ \\ {(x - 1)}^{2} + {(y + 2)}^{2} = {3}^{2} \\ \\ equating \: it \: with \\ \\ {(x - h)}^{2} + {(y - k)}^{2} = {r}^{2} \\ \\ h = 1 \\ k = - 2 \\ r = 3 \\ \\ center = \boxed{1} \: \boxed{ - 2} \: \: radius = \boxed{3}$

A potato chip manufacturer produces bags of potato chips that are supposed to have a net weight of 326 grams. Because the chips

When we take data at work, we always do it over a period of time. To me, just one sample set does not show enough data to come to that conclusion. Also it is one batch of bags. I think you would need to have an average of data from different batches & samples to prove your data is accurate and support your claim.
