The measure of angle A is 30 degree, the value of tan A is 1/√3 and the area of triangle ABC is 280.6 squared inches.
<h3 /><h3>What is the law of cosine?</h3>When the three sides of a triangle is known, then to find any angle, the law of cosine is used.
It can be given as,
Here, a,b and c are the sides of the triangle and A,B and C are the angles of the triangle.
Triangle ΔABC has side lengths of a = 18, b=18√3 and c = 36 inches.
- Part A: Determine the measure of angle A
Put the value, in the cosine law, the measure of angle A.
- Part B: Show how to use the unit circle to find tan A
Using the chart of unit circle, the value of tangent A can be found out. The tangent A is,
- Part C: Calculate the area of ΔABC.
Use the following formula to find area of ΔABC.,
Thus, the measure of angle A is 30 degree, the value of tan A is 1/√3 and the area of triangle ABC is 280.6 squared inches.

Answer:
Mr. Dairo can produce 20580 pieces of Papaya rosette in two weeks.
Step-by-step explanation:
Papaya rosette pieces on first day = 5890
Papaya rosette Pieces on second day = 7020
Papaya rosette Pieces of third day = 8150
Let
We can check if these numbers are part of a sequence.
In order to check, common difference will be found first.
It can be observed that the common difference is same. When the common difference is same, the sequence is said to be an arithmetic sequence.
The formula for arithmetic sequence is given by:
Putting the values
The formula for nth term can be used to find any term. As we have to find the number of papaya rosette pieces after two weeks which means that we need to find the number of pieces on 14th day.
So,
Hence,
Mr. Dairo can produce 20580 pieces of Papaya rosette in two weeks.
