In order to find the area of a polygon, all you have to do is follow the formula: area = 1/2 x perimeter c apothem. To sum it together, perimeter = the sum of the lengths of all the sides. So add 6, 16, 16, 6, 4, 6, 28, and 18! And then you have 100! Then multiply it by 1/2! So your answer should be 50. Please consider brainliest.

Please explain this answer ☹️

GuDViN [60]

Answer:

see explanation

Step-by-step explanation:

Note that cos315° = cos45° and sin315° = - sin45° and

cos45° = sin45° = $\frac{1}{\sqrt{2} }$ = $\frac{\sqrt{2} }{2}$

Hence

12(cos315° + isin315°)

= 12(cos45° - isin45°)

= 12( $\frac{\sqrt{2} }{2}$ - i $\frac{\sqrt{2} }{2}$ )

= 6 $\sqrt{2}$ - 6i $\sqrt{2}$

Solve Ax+Hy=K for x<br> Help!

denis23 [38]

Answer:

$x = -\frac{Hy + K}{A}$

Step-by-step explanation:

Step 1: Add -Hy to both sides.

$Ax + Hy - Hy = K - Hy$
$Ax = -Hy + K$

Step 2: Divide both sides by A.

$\frac{Ax}{A} = \frac{-Hy+K}{A}$
$x = -\frac{Hy+K}{A}$

Given any triangle in the plane, associate to each side an outward pointing normal vector of the same length as the side. Show t

Zigmanuir [339]

Let , a, b and c be the length of three sides of triangle, represented in terms of vectors as $\vec{a},\vec{b},\vec{c}$ .

Now, vector of same Magnitude acts as normal vector to each side.

So, equation of any vector p having normal q is given by

$\vec{p} \times\vec{q}$

Now sum of three vector and it's normal is given as

$=\vec{a} \times\vec{a}+\vec{b} \times\vec{b}+\vec{c} \times\vec{c}\\\\=0+0+0\\\\=0$

Cross product of two identical vectors is Zero.

$\rightarrow \vec{i} \times\vec{i}=0$
