Second transformation: a translation of vertex B to vertex Y
Hey there! :D
We know that <e <d and <c are supplementary. They are on a straight line and will equal 180 degrees.
We know F= 25 from the information.
Let's find a.
a= 4f+15
a= 4(25)+15
a= 115
Find b, which is supplementary to a and f.
25+115= 140
180-140= 40
We know that b is 40 degrees,
b and c are complementary, which means they equal 90 degrees.
90-40= 50
c= 50 degrees
Since b and e are vertical, they have the same measure.
b= 40 degrees.
So, 50+40= 90 degrees.
180-90= 90
<d= 90 degrees.
I hope this helps!

Answer:
Nolan took <u>100</u> seconds.
Step-by-step explanation:
Given:
Kong took 15%, percent fewer seconds than Nolan took to complete his multiplication timed test.
Kong took 85 seconds.
Now, to find the number of seconds Nolan take to complete the test.
Let the number of seconds Nolan take be 
Kong took = 85 seconds.
As, given Kong took 15%, percent fewer seconds than Nolan took.
Now, to get the number of seconds Nolan took:




<em>Dividing both sides by 0.85 we get:</em>

Therefore, Nolan took 100 seconds.
Two $20 bills = $40
$40 - $32.87 = $7.13
$7.13 is his change

Margin of error is a term used in Statistics to find the confidence interval. It is denoted by E.
Formula for E is:
Critical Value x Standard Deviation / (Square Root of Sample Size)

The critical value is determined by the type of test that is to be used for the given scenario and the confidence level.
