Draw two triangles has length 6 and width 9.The second has length 3x and width 9.Write at least three different expressions for
the sum of the areas of the rectangles.
1 answer:
Step-by-step explanation:
Three different expressions for the sum of the areas of the rectangles.
-The first is:
AREA = BASE X HEIGHT
2.A second way is:
AREA= Constant x (Variable + Constant)
<em><u>ADDITIONAL INFORMATION: </u></em>
A file with the drawing of the two triangles with their lengths and widths is attached.

Answer:
is isosceles.
Step-by-step explanation:
Please have a look at the attached figure.
We are <u>given</u> the following things:
Let us try to find out and
. After that we will compare them.
<u>Finding </u><u>:</u>
Side EG is a straight line so
is sum of internal
and external
<u>Finding </u><u>:</u>
<u>Property of external angle:</u> External angle in a triangle is equal to the sum of two opposite internal angles of a triangle.
i.e. external =
Comparing equations (1) and (2):
It can be clearly seen that:
The two angles of are equal hence
is isosceles.
