Answer:
<em>Yes, but only if BC ≅ DC; Option B</em>
Step-by-step explanation:
There are 4 possible ways to determine whether two triangles are congruent, and they are the following ;
ASA ( Angle - Side - Angle ),
SAS ( Side - Angle - Side ),
AAS ( Angle - Angle - Side ), and
SSS ( Side - Side - Side )
It is known here that we must prove these triangles congruence through SSS. A triangle can thus be made possible through the congruence of corresponding sides;
Now if we were to create these triangles it would be that BC and DC are, if the triangles were to coincide with one another, the apparent same length if it were that these two Δs really are ≅. Thus;
<em>Solution; Yes, but only if BC ≅ DC</em>
Answer: 1106.13 (2 decimal places)
Step-by-step explanation:
To work out the area of this composite shape you would have to put the two semi circles together to form a circle and work out the area of the circle (they have provided the radius which is 11in), then work out the area of the rectangle separately.
The formula for the area of a circle is πr^2 (pi x radius squared).
So when you put the numbers in the formula the area is πx11^2=380.1327111
Then to work out the area of the rectangle you would do base x height.
The height of the rectangle is the same as the diameter of the circle (the diameter is double the radius of a circle) which is 22in.
To find the area of the rectangle you do 22x33=726
So then to find the area of the whole shape you would have to add the area of the circle and the rectangle together.
726+380.1327111=1106.13 (2 decimal places).
