Answer:
27
Step-by-step explanation:
Just add all numbers together.
Answer:
To label 6.5 on a number line, put the plot between the 6 and 7.
Same thing goes for 8.5, except the plot would go between the 8 and 9.
8.5 > 6.5
Step-by-step explanation:
1.) Since 8.5 and 6.5 are decimals, they are not a whole number which is why they go right in the middle of the two numbers they are behind and in front of.
2.) > means greater than, and 6.5 is smaller than 8.5 therefore we use the greater than sign, pointed towards the 8.5.
I hope this helps! :)
Given:
A diagram of a circle O,
.
To find:
The measure of arc DC.
Solution:
According to the angle of intersecting chords theorem:
Angle at intersection of chords = Half of the sum of intercepted arcs.
Let
be the angle between the intersection of chords AC and BD.
(Linear pair)

Using the angle of intersecting chords theorem, we get



On simplification, we get



Divide both sides by 2.

Now,



Therefore, the correct option is C.
I’ll answer this later but use an equation 180 degrees
