Science > Mathematics > Trigonometry > Angle Measurement > Area of Sector In this article, we shall study to solve problems based on the area of the sector. Example – 01: Find the area of a sector of the circle which subtends an angle of 120° at the centre, if the radius of the circle […]
Science > Mathematics > Trigonometry > Angle Measurement > Length of an Arc In this article, we shall solve problems based on the length of an arc (arc length). Example – 01: Find the length of the arc of a circle of diameter 10 cm, if the arc is subtending an angle of 36° at […]
Science > Mathematics > Trigonometry > Angle Measurement > Angle Measurement In this article, we shall study the problems based on the interior angles of a polygon, and the angle between the hour hand and a minute hand of a clock. Example – 01: If xc = 405° and y° = – (π/12)c. Find x […]
Science > Mathematics > Trigonometry > Angle Measurement > Measurement of Angle in Radians In this article, we shall study to find a measure of an angle in radians and degrees. Express following angles in degrees, minutes, and seconds Degrees x 60 = Minutes Minutes x 60 = Seconds 74.87° 74.87° = 74° + 0.87° […]
