Please use statement and reason, not sin cos or tan. In rectangle ABCD the diagonals intersect each other at point O and ABD = 3

zvonat [6]

Answer:

8 in

Step-by-step explanation:

Rectangle has properties:
Diagonals are congruent
Opposite sides are congruent
All angles are right

<h3>Given</h3>

m∠ABD = 30°
AC = 16 in
BC = ?

<h3>Solution</h3>

<u>As per properties mentioned above we have:</u>

BC = AD
BD = AC = 16 in

ΔABD is right triangle with ∠B - 30°, ∠A- 90°, ∠D - 60°

Side opposite to 30 is half of the length of the hypotenuse

<u>AD is opposite to ∠B and BD is the hypotenuse, then:</u>

AD = 1/2*BD
AD = 1/2(16)
AD = 8 in

and

BC = AD = 8 in

Answer:

361/900

Step-by-step explanation:

$\left(-\dfrac{1}{6}+0.6\left(-\dfrac{1}{3}\right)+1\right)^2=\left(-\dfrac{1}{6}-0.2+1\right)^2\\\\=\left(1-\left(\dfrac{1}{6}+\dfrac{1}{5}\right)\right)^2=\left(1-\dfrac{5+6}{6\cdot5}\right)^2=\left(\dfrac{19}{30}\right)^2=\boxed{\dfrac{361}{900}}$
