Solve the measure of an angle is 161°. what is the measure of a supplementary angle?
lions [1.4K]
Supplementary angles sum up to 180°, suppose the supplement of 161° is x. Then
161+x=180
solving for x we subtract 161 from both sides
161-161+x=180-161
x=19
thus the supplement is 19°

I need this math problem done as soon as possible!
Vesna [10]

Answer:

See below

Step-by-step explanation:

<u>Parent function:</u>

  • y = 3ˣ

<u>Transformed function:</u>

  • y = 4(3)⁻²ˣ⁺⁸ + 6, (note. I see this as 8, sorry if different but it doesn't make any change to transformation method)

<u>Transformations to be applied:</u>

  • f(x) → f(-x) reflection over y-axis
  • f(-x) → f(-2x) stretch horizontally by a factor of 2
  • f(-2x) → f(-2x + 8) translate 8 units right
  • f(-2x + 8) → 4f(-2x + 8)  stretch vertically by a factor of 4
  • 4f(-2x + 8) → 4f(-2x + 8) + 6 translate 6 units up

Please help w/ math!

You need to convert 3 lb, 6 oz into all ounces. To do this, know that 16 ounces is 1 pound.
(3pounds)(16 oz/1 pound)
This cancels out the pounds, and leaves you with 48ounces, then add the 6 ounces you already knew of. You now have 54 ounces, which is "D"

2. In the 2016 presidential election, most Americans were inundated with poll results, all of which reported a margin of error.
Fiesta28 [93]

Answer:

Throughout the clarification segment elsewhere here, the definition including its query is mentioned.

Step-by-step explanation:

  • The error margin applies to the difference between the results of this survey as well as the real estimates.
  • This may occur for several factors, such as limited sample size, incomplete survey, people's biased answers, etc.
  • It shows us where the outcomes of this study are not reliable and 100% right and, for several different reasons, there seems to be a disparity between some of the published and real statistics.

In addition to making audiences and people believe that perhaps the recorded results could not be considered as 100 percent reliable so there's still a variety of errors throughout themselves, it is important to incorporate this detail in polling data.
