Answer:
178
Step-by-step explanation:
The area of the rectangle is 6x25=150.
The area of the two semicircles on the sides is equal to the area of one circle with a radius of 3, so the area is 
which is approximately 28.27.
150+28.27=178.27
There you go. Depends on which value of pi you use.
The first pair of triangles are similar.
Triangle ABC is similar to Triangle PQR.
I used the SSS theorem of congruency.
( side - side - side) since I knew the sides were equal I knew that they were congruent.
----------------------------------------------------------
The second pair of triangles are similar too.
Triangle ABC is similar to Triangle DEF.
I also used the SSS theorem of congruency.
Since I knew what the sides were, I did some calculations and they all equalled 6...

I hope that helps you out!! Any more questions??
That would be 106.5 degrees
Step-by-step explanation:
2n is the answer because you combined the two variables then you do 20n plus 20n minus. 10 equals 50 then subtract 10 from 50 and get forty the divide that by 20 which equals 2
