Answer: (x,y) (-y,x)
Step-by-step explanation:
The complete question in the attached figure
we know that
area of semi circle=pi*r²/2
diameter=5 ft
radius r=5/2----> 2.5 ft
so
area of semicircle=pi*2.5²/2-----> 9.8125 ft²
<span>the area of each stained glass section=area semicircle/3
</span><span>the area of each stained glass section=9.8125/3----> 3.27 ft</span>²---> 3 ft²
the answer is3 ft²
There are an unknown number of possible outcomes. To figure this out all we need to do is multiply the amount of options per category to get the number of possible combinations.
In this case, there are 3 choices of food items and 3 choices of drinks.
Therefore, we need to multiply 3 by 3 to get the combinations.
3 times 3 equals 9
In conclusion, there are 9 possible combinations to be made from the choices presented.
<h2>Hello!</h2>
The answer is: All of the above.
<h2>Why?</h2>
First, we need to know that both triangles have the same dimensions:
If two triangles have the same side length, the angles will be the same two.
Hence,
If both triangles have the same side length, they are congruent according to the Side-Side-Side(SSS) triangle congruence theorem. It also means that:
Both triangles have the same angles, meaning that its angles are congruent. If there is at least one angle which is congruent, and there are at least two sides that are equal for both triangles, the triangles are congruent according to the Side-Angle-Side (SAS) triangle congruence theorem.
If two angles and at least a side are congruent, the triangles are congruent. According to the Angle-Side-Angle(ASA), if two angles and the included side are congruent, the triangles are congruent.
For this case, each theorem will be satisfied because the triangles have the same side length, meaning that all of the above theorem can prove that the triangles ABC and DEF are congruent.
