Which one of the following equations is correct? cos 45° + sin 45° = 1 [1 – sin (-30°)] [1 + sin 30°] = cos^{2} 30° sin 50° + cos (-40°) = 0 cos 90° = 2 cos 90° sin 60° 2. Which one of the following statements is NOT correct? If the sum of angles on an n sided polygon is n right angles, then n = 4 No regular polygon can have interior angle equal to 140° No regular polygon can have interior angle equal to 110° A regular polygon with 180 sides has each interior angle equal to 178° 3. In the above figure CD is parallel to AB. The angle y is equal to: 40° 60° 80° 100° 4. The earth makes a complete revolution about its axis in 24 hours. The angle through which it will turn in 4 hours and 40 minutes, is equal to: 60° 70° 120° 50° 5. Which one of the following empirical relations is correct in respect of a moderately asymmetrical distribution? 3 median = 2 mean – mode mean – median = 3(mean – mode) 2 mean = 3 median – mode 2 mode = 3 median – mean 6. If in a triangle ABC, ÐB = 2 ÐC and the bisector of ÐB meets CA in D, then the ratio BD: BC would be equal to: AB: AD AB: AC AD: AC AC: AB 7. ÐABC is equal to 45° as shown in the above figure. If AC/AB = Ö2, then ÐBAC is equal to: 95° 105° 10° 110° 8. In a triangle ABC, BD and CE are perpendicularg on AC and AB respectively. If BD = CE, then the triangle ABC is: isosceles right-angled equilateral scalene 9.
