Answer:
368 sq. units.
Step-by-step explanation:
We have a square of side lengths 20 units and we cut four congruent isosceles right triangles from the corners of the square.
Now, the four isosceles right triangles have one leg equal to 4 units.
Therefore, the area of four triangles = sq. units.
Now, we have the area of the given square is (20 × 20) = 400 sq. units.
Therefore, the area of the remaining octagon will be (400 - 32) = 368 sq. units. (Answer)
-100 is rational.
-100 can be turned into a fraction by doing the following...
Just put 1 underneath -100 and you get
So that means it is rational since it can be a fraction!
To determine the number of possible arrangements for 6 out of 8, we should use combinations. That is
ₐC₆ = 8!/(6!2!)
Answer: b. Combination
Answer:
B:25°
Step-by-step explanation:
Now gets bisected by .
Since, the angle is bisected, this means that the angle is split into two equal parts or the angle is halved.
We know that one of the angles is so the other angle has to be also.
Hence, the .
