A radius perpendicular to a chord bisects the chord, so the answer is twice 4.5
Answer: C. 9
Some key definitions:
<u>Reflexive property:</u> angles, line segments, shapes are congruent to themselves. Its easier to think of a shape: if you have a circle, then this circle is equal to itself.
<u>Symmetric property:</u> you can interchange the equal signs of an equation. So think of a=b is the same as b=a, its just the same thing written in a different order.
<u>Transitive property:</u> If a=b, and b=c, then a=c. Basically think of it as a=b=c, all of these variables are the same as each other.
So for the first clue, you have the reflexive property.
The second clue is the symmetric property.
The third clue is the transitive property.
Answer:
x=65°
Step-by-step explanation:
Full circle is 360°,then 360-90-180=90,and
x+25=90
x=90-25
x=65°
Answer:
The answer is 181
Step-by-step explanation:
PEDMAS
1 x 1 + 9 x 20
1 x 1 = 1
1 + 9 x 20
9 x 20= 180
1+180
which equals 181
This polynomial is a difference of two squares.
A difference of two squares factors into the product of a sum and a difference.
