Answer:
Step-by-step explanation:
The relevant relations are ...
- an arc has the same measure as the central angle it subtends
- angles of a linear pair are supplementary (total 180°)
- an inscribed angle has half the measure of the arc it subtends
- the total of arcs of a circle is 360°; of a semicircle, 180°
__
arc CB has the measure of central angle COB: 64°
angle AOC is the supplement of angle COB: 180° -64° = 116°
arc AD is twice the measure of inscribed angle ABD: 2×13° = 26°
arc DFB is the supplement of arc AD: 180° -26° = 154°
angle CDB is half the measure of arc CB: 64°/2 = 32°
In following manner we can write an equation to represent a real-world situation
Step 1: From the problem statement, determine the known and unknown quantities.
Step 2: Using keywords, ascertain the connection between the known and unknown quantities.
Step 3: Create an equation to show how the known and unknown quantities relate to one another.
There are various mean types in mathematics, particularly in statistics. Each mean helps to summarize a certain set of data, frequently to help determine the overall significance of a specific data set.
A mathematical statement known as an equation is made up of two expressions joined together by the equal sign. A formula would be 3x - 5 = 16, for instance. When this equation is solved, we discover that the value of the variable x is 7.

Since they have the same x-coordinate, you can just find the difference between the y-values.
7 - (-6) = 7 + 6 = 13
It'd be a little more complicted if they didn't have the same x or the same y cooridnates.
Answer:
45
Step-by step
What do we already know about the equation?
We know that they EACH bought a hockey puck($17) and 2 shirts
Half of 214 is 107. So they had to have spent 107 separately
So we make the equation and let s represent shirts
2s + 17 = 107
- 17 -17
2s= 90. DIVIDE by 2
s = 45
