Answer:
Step-by-step explanation:
There are 30 students in a math class.
Only 8 students submitted their homework.
So those did not submit the homework were 30 - 8 = 22
The fraction of the students who did not submit the homework were 
=
Answer:bull has x
Kanika has 10x+9
X_2
Step-by-step explanation: we express bulbul as x since we dont know the actual identity
The statement Kanika has ten times more makes u multiply by 10 then add the ninewe equate kanikas amount subtract 29 by 9 then divide by 20 getting x
<span>A regular polygon is, by definition, a polygon with congruent interior angles and sides. Thus, if we rotate n-gon about its centre, we will repeat the polygon n times before it comes back to its original position.
a. The interior angles are congruent to their exterior angles.
This means that all angles are 90 degrees, so
true for a square or rectangle,but FALSE for a 25-gon.
b.All the diagonals are congruent.
It is true for all regular polygons, but not sufficient to make the polygon regular.
Counter example: A rectangle has all diagonals congruent, but it's not a regular quad. So FALSE.
c.Opposite pairs of sides are parallel.
All even-number sided regular polygons will satisfy this property, but not sufficient to make a polygon regular. Counter example: A rectangle with different adjacent sides. So FALSE.
In the case of a 25-gon, there are no "opposite" sides.
d. All interior angles and all sides are congruent.
This will undoubtedly create a regular polygon, since it satisfies the definition of a regular polygon. If we rotate it about its centre, we can repeat the same 25-gon 25 times. So TRUE</span>
Answer:
That would be opposite over adjacent, or 12/5. tan=o/a

Answer:
A
Step-by-step explanation:
6 + 13 = 19, this is TRUE.
So x = 6 In x + 13 = 18 would be FALSE.
The answer is A. No, because 6 + 13 = 18 is not true.
