An aeroplane flies horizontally due east at a constant speed of 240km/hr, From a point P on the ground, the bearing of the plane at one instant is 311 T, and 3 min later, the bearing of the plane is 073 T, whilst its elevation then is 21. If h metres is the altitude of the plane, show that h =...

Yes ofc, The answer is: 137m

A tower stands at the foot of a plane which is inclined to the horizontal at an angle of 12. A line 100m in length is measured straight up the incline from the foot of the tower. It is found that at the end of this line the tower subtends an angle of 62. Calculate the height of the tower to the...

Two perpendicular chords AB and CD of a circle, centre O, intersect at E. Prove that angle AOD + angle BOC=180º.

Physics is just amazing

Loool... How much does it cost?
