<u>Step-by-step explanation:</u>
and 
Using substitution method we get:

1) Tan45 = 1
2) Sin70 = 0.9397
3) Cos30 = 0.8660
4) Cos20 = 0.9397
Given:
Center of the circle is O.
A and C are points on the circle.
Solution:
Question 1.
The piece of the circle between the points A and C is called an arc.
Question 2.
AOC is a acute angle. It is located in a center of the circle.
Therefore AOC is a central angle.
Question 3:
The line segment joining center to boundary of the circle is called the radius.
Therefore the line segment OC is a radius of the circle.
Answer:
Final answer is approx 6.644 years.
Step-by-step explanation:
Given that a company sold 5.75 million motorcycles and 3.5 million cars in the year 2010. The growth in the sale of motorcycles is 16% every year and that of cars is 25% every year.
So we can use growth formula:
Then we get equation for motorcycles and cars as:
Now we need to find about when the sale of cars will be more than the sale of motorcycles. So we get:
Hence final answer is approx 6.644 years.
