Can Someone Explain The Process Of Getting To Angle A? I Know The Answer Is 44.1 But I Need To Show My

Answers

Answer 1

Answer:

Step-by-step explanation:

First you have to calculate CB in order to use sin law to calculate ∠A

CB=[tex]\sqrt{18.4^{2} -13.2^{2} }[/tex]

CB=12.8(correct to nearest tenth)

After that, use sin law to calculate ∠A,

[tex]\frac{18.4}{sin90} =\frac{12.8}{sinA}[/tex]       or    [tex]\frac{sin90}{18.4} =\frac{sinA}{12.8}[/tex]

sinA=0.695...

A=44.079...

  =44.1(corrext to the nearest tenth)

Is that clear enough for you?

Find the term that must be added to the equation x2−2x=1 to make it into a perfect square.

Answers

Answer:

The perfect square ( x -1 )² = 2

Step-by-step explanation:

Explanation:-

Given equation  x² - 2 x = 1

              ⇒        x² - 2 x + 1 -1 = 1

             ⇒        x² - 2x + 1² = 1 +1

             ⇒     ( x -1 )² = 2

The equation LaTeX: p=5000\cdot2^tp = 5000 ⋅ 2 t represents the population of an invasive fish species in a large lake, years since 2005, when the fish population in the lake was first surveyed.
