Answer:
 is isosceles.
 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
 and  . After that we will compare them.
. After that we will compare them.
<u>Finding </u> <u>:</u>
<u>:</u>
Side EG is a straight line so 
 is sum of internal
 is sum of internal  and external
 and external 
 
 
<u>Finding </u> <u>:</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
 are equal hence  is isosceles.
 is isosceles.

-------------add
2x = 6
x = 3
X - Y =4
3 - Y = 4
Y = 3 - 4
Y = -1
solution (3 , -1)</span>
        
             
        
        
        
A cause and effect relationship exist between two variables, when one 
variable event is made to happen by the other variable.
The situation which best shows causation is option <u>B) The amount of time a </u>
<u>cell phone is used affects the charge of the battery</u>.
Reasons:
Causation is the condition in which the occurrence of an event is caused by 
or contributed to by another event. Such that the incident or observation 
identified as the cause is responsible for the event, while the the 
occurrence of the event depends on the cause being put in place.
- Option A) A rectangle of a given width can have different dimensions of length
- Option C) Milkshakes and ice cream bars can have different customer base, such that the number of milkshake and ice cream bars sold can be equal
- Option D) The balls used in a soccer match are provided by the officials of the game
 
Therefore;
- The situation which shows causation is B) <u>The amount of time a cell phone is used affects the charge of the battery</u>.
The option is correct because, a cell phone is powered by battery, and 
therefore, the more the cell phone is used, the battery power is used up 
and therefore, the charge on the battery is reduced.

Answer:
This might get confusing but bear with me.
The top two are correct, leave them where they are. The 6th one down is step three, the 8th one down is step four, the 3rd one down is step five, the 4th one down is step six, the 7th ne down is step seven so leave it alone, and the 5th one down is step 8.
