Trigonometry is the branch of mathematics that studies the relationship between the sides lengths and angles in a triangle.
<h3>What is trigonometry?</h3>
Your information is incomplete as the triangles aren't given. Therefore, an overview will be given.
It should be noted that trigonometry simply means the branch of mathematics that is concerned with angles and their application to calculation.
In this case, studies the relationship between the sides lengths and angles in a triangle. The there basic functions in trigonometry are sine, cosine, ad tangent.

1 year = 365 days.
1 day = 24 hours.
1 hour = 60 minutes.
First convert the hours and minutes in Jupiter orbit to days:
14*60 = 840 +9 = 849 minutes.
849 / 60 = 14.15 hours.
14.15 / 24 = 0.59 days.
Jupiter's orbit is 4332.59 days.
Now divide that by 365 for the number of years:
4332.59 / 365 = 11.87 years.
Answer: $0.24
Step-by-step explanation:
9.5 inches --> $2.28
1 inch--->X
now cross multiply it and get,
9.5X = 2.28*1
X = 2.28/9.5
so its $0.24 per inch
Answer:
(a) It is an experiment.
(b) Group III has been tested to compare the effect of tea
Step-by-step explanation:
24 volunteers are randomly selected to one of the three groups.
Group I drinks two cups of hot black tea without milk
Group II drinks two cups of hot black tea with milk
Group III drinks two cups of hot water but no tea.
At the end of the month, the researchers measured the change in each of the participant's heart health.
The average change of health status of three Groups can be measured and let it be X1', X2' and X3'. We can set up the hypothesis of no difference of heart health i.e H0 : µ1 = µ2 = µ3 against the alternative hypothesis that they are not equal. As the sample size is less than 30, we can use t-statistic.
Under the above logic, (a) it is an experiment.
(b) Group III has been tested to compare the effect of tea or to have comparison between GroupI and Group III.
