Answer:
True
Step-by-step explanation:
First two points are inverse of last two points, all points reflects each other over y = -x
For this case we have that the area of the triangle is given by:

Where:
b: It's the base
h: It's the height
We have to:

The atura will be given by:

So, the area is:

Answer:
144
Answer:
<em>x = 59</em>
Step-by-step explanation:
<u>Equations</u>
The interior angles formed by the sides of a quadrilateral have measures that sum to 360°.
The image shows a four-sided polygon and its four angles measures, thus we sum them all and equate the sum to 360:
x + x + 2x + 3 + 2x + 3 = 360
Simplifying:
6x + 6 = 360
Subtracting 6:
6x = 354
Dividing by 6:
x = 354/6
x = 59
Answer:
l=40
Step-by-step explanation:
The area is calculated as
A = wl
1200=30l
1200/30=l
40=l
