Answer:

162√3.

Step-by-step explanation:

Area = 1/2 * p * q  where p and q are the diagonals.

Here p = 2*9 = 18 and we need to find q.

tan 60 = 0.5q/9

0.5q = 9 tan 60 = 9*√3

q = 18√3

So the area of this rhombus

= 1/2 * 18*18√3

= 162√3

=

Answer:    \bold{x^2-\dfrac{181}{13}xy+12y^2=0}

<u>Step-by-step explanation:</u>

\tan \theta =\dfrac{y}{x}\quad \longrightarrow \theta=\tan ^{-1}\bigg(\dfrac{y}{x}\bigg)

\text{Given:}\quad \theta =\tan^{-1}\bigg(\dfrac{1}{13}\bigg)\quad \longrightarrow x=13,y=1

Insert x = 13 and y = 1:

x² + 2hxy + 12y² = 0

(13)² + 2(13)(1) + 12(1)² = 0

169 + 26h + 12 = 0

       26h + 181 = 0

                26h = -181

                    h=-\dfrac{181}{26}

\text{Insert:}\ h=-\dfrac{181}{26}

x^2 + 2\bigg(-\dfrac{181}{26}\bigg) xy + 12y^2 = 0

\bold{x^2 -\bigg(\dfrac{181}{13}\bigg) xy + 12y^2 = 0}

What name best describes this shape?
EastWind [94]

Answer: Quadrilateral

Explanation:

Any four sided polygon is considered a quadrilateral since "quad" means "four". You can think of a quad bike, which has four wheels, to help remember this math term.

Usually in problems like this, we'll be given information about if certain sides are parallel or the same length. However, we don't this info, so we cannot narrow down this classification anymore.
