Answer:

36, 16, 81, and 64.

Step-by-step explanation:

These numbers are perfect squares in that when you find the square root of that number it is a whole number. For example \sqrt{36} = 6 because 6 × 6 =36.

72 is not a perfect square because \sqrt{72} = 8.48528137424, which isn't a whole number.

Answer:

  11.6 cm

Step-by-step explanation:

As the page title tells you, the Pythagorean theorem must be applied more than once. As you know, it tells you the square of the hypotenuse is the sum of the squares of the two sides.

  AD² = ED² +EA²

  EA² = AD²-ED² = 7² -6² = 13

  EA = √13 ≈ 3.606

__

  CD² = ED² +EC²

  EC² = CD² -ED² = 10² -6² = 64

  EC = √64 = 8

__

The length of the horizontal diagonal is ...

  AC = EA +EC = 3.6 +8 = 11.6 . . . cm

inn [45]

sketch the situation

a trigonometric function that is a relation between the angle of elevation and the 2 sides of the rectangles is the tan

\tan \theta=\frac{opp}{adj}\tan \theta=\frac{20}{30}=\frac{2}{3}

find the inverse

\begin{gathered} \tan ^{-1}(\frac{2}{3})=\theta \\ \theta=33.69º \end{gathered}

after rounding the angle of elevation is 34º.
