Answer:
Step-by-step explanation:
Opposite angles of an inscribed quadrilateral are supplementary, so ...
m∠A + m∠C = 180°
Substituting the given expressions, we have ...
(3x +6)° + (x+2)° = 180°
4x +8 = 180 . . . . . . collect terms, divide by °
x +2 = 45 . . . . . . . . divide by 4
3x +6 = 135 . . . . . . multiply by 3
This is the value of angle A in degrees, so ...
m∠A = 135°
Answer:
if angle 2 is 117 degrees, angle 3 is supplemental and would be 63 degrees.
180-117=63
The sample mean for students with a grade point average of 3.0–4.0 is greater than students with grade point average of 2.0 - 3.0, the results tend to
<h3>How to interpret Garret studies?</h3>
From the question, we have the following highlights
- The sample size is large enough
- The sample is at random
- Students who have a grade point average of 3.0 - 4.0 sleep for an average of 6.8 hours
- Students who have a grade point average of 2.0–3.0 sleep for an average of 6.4 hours
- There are no outliers
From the above highlights, the sample mean for students with a grade point average of 3.0–4.0 is greater than students with grade point average of 2.0 - 3.0
This is because 6.8 is greater than 6.4
This means that Garret's theory about the hours of sleep is correct
