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.
Answer:
Step-by-step explanation:
Rounding means making a number simpler but keeping its value close to what it was. The result is less accurate, but easier to use. Example: 73 rounded to the nearest ten is 70, because 73 is closer to 70 than to 80. But 76 goes up to 80. There are many ways to round.
Answer:
x= 1, -1
Step-by-step explanation:
If the rectangle ABCD is similar to rectangle EFGH, side CD is proportional to the side
C. GH
The order of the letters in naming the rectangle gives us which sides are adjacent in rectangle and which sides correspond to the other rectangle.
