Number 2 is the correct answer
Angle x is the same as the angle opposite it so 63 degrees
angle y = 180 - 72 - 63 = 45 degrees
angle z is the same angle shown at point B so 72 degrees
Answer:
See explanation
Step-by-step explanation:
This question requires a list of options.
Since, there are none; I'll give a general explanation to answer this.
We have that:

The general format of an equation in terms of f and c is:

Where
and 
A true statement about the function above is:
The slope of the equation is 14
This means that at every minute, there's an additional 14 chirps from the cricket.
Another true statement about the function is that:
The y intercept is 40.
This means that the initial number of chirps by the cricket is 40
i.e. At time, c = 0 minutes.
There are 40 chirps.
A likely question could be to determine the number of chirps in (say) 5 minutes.
This means that:

Substitute 5 for c in 



This implies there are 110 chirps in 5 minutes
Answer:

Step-by-step explanation:
Given


Required
Determine the total number of markers
First, we need to determine the ratio of black to blue such that


Multiply the ratio by 5


By direct comparison:


The above shows that:

So:
