Find the Area of the Garden (Must show work!!!)

sesenic [268]

Answer:

162 ft²

Step-by-step explanation:

The missing side of the garden is the hypotenuse of a triangle with legs:

(80 - 70) = 10 ft and (40 - 15) = 25 ft

The length of the side is:

$\sqrt{10^2+ 25^2} = \sqrt{725}$ ≈ 27 ft

The area of the garden is:

A = 27*6 = 162 ft²

Angle 3:
62+47=109
All angles in a triangle add to 180 degrees, so 180-109= 71 degrees
Angle 2:
Angles in a straight line always add to 180 degrees too,
so 180-62= 118 degrees
Angle 1:
Again, angles in a triangle add to 180,
so 180-22-118= 40 degrees

Angle 1: 40
Angle 2: 118
Angle 3: 71
Hope that helps :)

Let a be an mn matrix, and let u and v be vectors in irn with the property that au = 0 and av = 0. explain why a(u + v) must be

tatiyna

$\mathbf{Au}=\mathbf0$
$\mathbf{Av}=\mathbf0$

$\implies\mathbf{Au}+\mathbf{Av}=\mathbf0$
$\implies\mathbf A(\mathbf u+\mathbf v)=\mathbf0$

Multiplying by scalars $c,d$ won't change this fact.
