In the evening, a dark and menacing storm quickly gathered. FIRST COMES THE WIND Winds beat against the houses with a speed and fury that Prashant had never witnessed before. DESCRIBING THE FURY - FOLLOWED BY THE RAIN Heavy and incessant rain filled the darkness, ancient trees were uprooted and crashed to the earth. HOUSES OF PEOPLE GOT WASHED AWAY Screams rent the air as people and houses were swiftly washed away. WATER CAME INSIDE THE FRIEND’S HOUSE BUT DID NOT WASH AWAY THE HOUSE AS IT WAS STRONGLY BUILT The angry waters swirled into his friend’s house, neck deep. The building was of brick and mortar and was strong enough to survive the devastation of the wind’s velocity of 350 km per hour.
A 16-meter-long rope is stretched from the ground to the top of a house, forming a 30° angle with the ground. Determine the height of the house.
- Find the value of sin²50° + sin²40°.
Simplify the following trigonometric expression:
8 cos 40° cosec 50° − 2 cot 30° cot 60°
- cosx/(1 – sinx) + cosx/(1+ sinx) = 4, 0 o < x < 90 o , then the value of (tanx + cosecx)

If (5sinx - cosx) = 2√2sinx, then find the value of 'tanx'
If 2x = cosec @ and 4/x = cot @ then the value of 2(x ² - 1/x ² ) is
If √3cosec 2x = 2, then the value of x:
- If sin(A + B) = sinAcosB + cosAsinB, then the value of sin75° is
2 × Tan 30° / (1 + Tan2 30°) equals:
