Let the initial speed of the bike be ‘x’ km/hr Therefore, speed of the car = 1.15x km/hr According to the question, 10 × 1.15x – (8x + 2 × 1.3x) = 27 => 11.5x – 10.6x = 27 => x = 27/0.9 = 30 km/hr
If A and B are complementary angles, then the value of-
sin A cos B + cos A sin B – tan A tan B + sec 2
Simplify (cos20°+sin 20°) /(cos20°-sin20°)
Simplify: sin (A + B) sin (A - B)
What is the value of cosec30° sec30°?
The minimum value of 77 sin θ + 36cosθ is
If tan A = 4/3, 0 ≤ A ≤ 90°, then find the value of sec A.
Simplifies-
(1 + tan²A) + (1+ 1 /tan²A)
[A] 1/ (sin²A-sin4 A)
[C] 1/ (cos2 A-sin4 A)
[B]...
