Trigonometry Quiz 1 Trigonometry Quiz for Class 10 1 / 10 1. The two legs AB & AC of right-angled ABC are in the ratio 1:3, what will be the value of sin C?(Hint: Legs referred to the sides of a right-angled triangle other than hypotenuse) √10 1/√10 3/√10 1/2 2 / 10 2. 30° 60° 45° none of the above 3 / 10 3. If cos A = 4/5, then the value of tan A is 3/4 4/5 3/5 5/3 4 / 10 4. If sinA = 1/2, then the value of cotA is √3 1/√3 √3/2 1 5 / 10 5. Given that sin a = √3/2 and cos b = 0, then the value of b - a is 0° 90° 60° 30° 6 / 10 6. If ∆ ABC is right-angled at C, then the value of sec(A + B) is(Hint: Use sum property of triangle concept) 0 1 1/2 not defined 7 / 10 7. If sin α = 1/2 and cos β = 1/2 , then the value of (α + β) is 0° 30° 60° 90° 8 / 10 8. 2/3 1/3 1/2 3/4 9 / 10 9. In the adjoining figure, the length of BC is 1/2 cm 2√3 cm 3√3 cm 3 cm 10 / 10 10.
