Solved Examples

1. Draw 60° Angle Using a Protector.

Solution: Draw a straight line named PQ and point at Q. Q represents the vertex of the angle. Outing point Q at the center of the protector, baseline the protector along with QP. Mark 60 degrees on the scale of the protector and draw a small dot at the edge. Join the dot with vertex Q with the help of a ruler to form the second arm named QR. Mark the angle with a small arc and write 60°.

2. Convert the following degrees into radians –

a) 36° b) 225° c) 7 degree 30 minutes

Solution:

a. We know, angle in radians = π/180* Angle in degrees.

Therefore, angle in radians = 36° * π/180

= π/5

b. We know that, angle in radians = π/180 * angle in degrees.

So, angle in radians = π/180 * 225°

= 5π/4

c. We know, angle in radians = π/180 * angle in degrees.

Angle in radians = angle in minute/60

Therefore, total angle = 7 + 30/60 = 7.5

So, angle in radians = 7.5° * π/180

= π/24

3. The Sum and Difference of Two Acute Angles of a Right-angled Triangle are π/2 and

π/5. Find Out the Value of Two Acute Angles.

Solution: We know, angle in degrees = 180/π * angle in radians.

So, π/5 * π/180 = 36°

π/2 * π/180 = 90°

According to the conditions, if the angles are x and y –

X+Y = 90°…….(1)

X-Y = 36°…….(2)

Solving (1) and (2), we are getting –

2X= 126°

Or, X= 63°

Putting value of X in (1) –

63° - Y = 90°

Or, Y = 27°

Therefore, the value of the two acute angles is 63° and 27°.

4. What are the Sexagesimal system and the Centesimal system as explained in chapter 14 of class 11 RS Aggarwal?

As mentioned in class 11 Chapter 14 of RS Aggarwal, Sexagesimal System comprises a system of measuring angles where eagles are measured in degrees, minutes, and seconds. It is also known as the English system. A degree, according to the Sexagesimal System, is one part out of 90 in which a right angle is divided into. A sexagesimal minute is obtained by dividing a degree into 60 equal parts. On the other hand, According to the Centesimal System, an angle is measured in seconds, minutes, and grades. Here, a right angle is divided into 100 equal parts instead of 90 and each part is called a grade which on being divided into 100 again gives centimeters.

5. How many chapters are there in the Class 11 CBSE Class 11 syllabus for mathematics?

The Class 11 mathematics syllabus for the CBSE board consists of 16 chapters divided into 6 units. These units are carefully constructed to cover a diverse range of topics for class 11 students so that they are prepared for the topics in class 12 and also for the entrance exams like JEE. the sex units in class 11 Mathematics syllabus CBSE board are: Sets and Functions, Algebra, Coordinate Geometry, Calculus, Mathematical Reasoning, and Statistics and Probability.
