An arc of a bridge is semi-elliptical with the major axis horizontal. If the length of the base is 9m and the highest part of the bridge is 3m from the horizontal, then prove that the best approximation of the height of the acr 2 m from the center of the base is `8/3mdot`

In a model, it is shown that an arc of a bridge is semi-elliptical having major axis horizontal. If the length of the base is 9 m and the highest point of the bridge is 3 m from the horizontal , the best approximation of the height of the arch, 2 m from the centre of the base is approximately :

In a model, it is shown that an arc of a bridge in semi-elliptical with major axis horizontal. If the length of the base is 9 m and the highest part of the bridge is 3 m from the horizontal, the best approximation of the height of the arch at 2 m from the centre of the base is

In a model. It is shown that an arch of abridge is semi-elliptical with major axis horizontal if the length of the base is 9m and the heightest part of the bridge is 3m from the horizontal, then the best approximation of the height of the arch , 2m from the centre of the base is

In a model, it is shown that an arc of a bridge is semi elliptical with major axis horizontal. If the length of the base is 9m and the highest part of the bridge is 3m from the horizontal, then the height of the arch, 2m from the centre of the base is (in meters)

If the horizontal distance of the boat from the bridge is 25 m and the height of the bridge is 25 m, then find the angle of depression of the boat from the bridge.

The arch of a bridge is the shape of a semi ellipse having a horizontal span of 40 m and 16 m highest the centre. How high is the arch, 10m from the right/ left of the centre.

Find the angle of depression of a boat from the bridge at a horizontal distance of 25 m from the bridge, if the height of the bridge is 25sqrt3 m____
