Answer:
hard to go without a graph see explanation
Step-by-step explanation:
from each point, count har far away it is from the dotted mirror line and then count that many in the opposite direction.
for example, the spikey point at the bottom is 3 units below the mirror line so count 3 units above the mirror line and that is where other point will be
A) 2007
b) 120
c) the donations are decreasing as years increase
So first you have to multiply 21 by .1 to figure out ten percent
you then get 2.1
you add 21 and 2.1 together and get 23.1
then since you have 3 people you divide by 3 and get 7.7
therefor 7.7 is your answer
(a). All four sides are equal and the angles are right-angled (90 degrees).
(b). A quadrilateral has no pairs of parallel sides is a Kite and irregular trapezium.
(c). A triangle having one pair of equal sides and one pair of equal angles is an isosceles Triangle.
<h3>What is geometry?</h3>
One of the first areas of mathematics is geometry, along with arithmetic. It is focused on spatial characteristics that relate to the proximity, size, shape, and relative placement of objects.
(a). Two features that make the shape square are all four sides equal and the angles are right-angled (90 degrees).
(b). A quadrilateral has no pairs of parallel sides is a Kite and irregular trapezium.
(c). A triangle having one pair of equal sides and one pair of equal angles is an isosceles Triangle.
