Question
A truck travels 32 km North, then it turns West and
travels 22 km, then it turns South and Travels 55 km, then it turns to its left and travels 22 km. Where is it now with reference to its starting position?Solution
Required distance = 55 – 32 = 23 Km.
What is the value of [(tan 5θ + tan 3θ)/4 cos 4θ (tan 5θ – tan 3θ)]?
- If sin (3A − 4B) = (1/2) and cos (A + B) = (√2/2), where 0° < A, B < 90°, then find the value of ‘A’.
sin2 7˚ + sin2 9˚ + sin2 11˚ + sin2 12˚ + ……… + sin2 83˚ = ?
If cos2B = sin(2B - 30°), then find the measure of 'B'.
In triangle ABC, ∠A - ∠B = 16 ° , whereas ∠A - ∠C = 8 ° , find ∠B.
