Olympiad Workshop_Assignment-14_IOQM Corporate Office : Aakash Tower, 8, Pusa Road, New Delhi-110005 Ph.: 011-47623456 Olympiad Workshop_Assignment-14_IOQM Topic : Basic Trigonometry and Properties of Triangle cos4 sin4 1 , then the value of cos 4 sin4 1. Given that 2. In the triangle ABC, B = 90 , C = 20 , D and E are points on BC such that ADC = 140 and AEC = 150 . cos2 sin2 cos2 sin2 is Suppose AD = 10. Then BD. CE is equal to 3 1 64 sin2 20 is 3. The value of 4. In triangle ABC, AB = 32 cm, AC = 36 cm and BC = 44 cm. If M is the midpoint of BC, then the length of AM in 2 sin 20 2 cos 20 cm, is 5. In a triangle ABC the length of the altitudes AD and BE are 4 and 12 respectively. Then the largest possible integer value for the length of the third altitude CF is 6. In ABC, A = 2 B. Let a, b, c be the lengths of its sides BC, CA, AB, respectively. Then the value of a2 b2 bc is equal to 3 5 and cosB . If the value of 1 cosC is , then the value of is 5 13 65 7. In a triangle ABC, sin A 8. The number of acute-angled triangles (i.e., all angles are less than 90 ) in which all angles (in degrees) are positive integers and the largest angle is three times the smallest angle, is Corporate Office : Aakash Tower, 8, Pusa Road, New Delhi-110005 Page [1]
