That is, we have to find the length of BC.Here AB represents height of kite from the ground, BC represents the distance of kite from the point of observation.In the right triangle ABC the side which is opposite to angle 60 degree is known as opposite side (AB), the side which is opposite to 90 degree is called hypotenuse side (AC) and remaining side is called adjacent side (BC).

So, the height of the balloon from the ground is 173.2 m.You can also visit the following web pages on different stuff in math. (This affects whether 72 m or something a little less is used in the calculation). Here, AB represents height of the building, BC represents distance of the building from the point of observation.In the right triangle ABC, the side which is opposite to the angle 60 degree is known as opposite side (AB), the side which is opposite to 90 degree is called hypotenuse side (AC) and the remaining side is called adjacent side (BC).

In the right triangle ABC the side which is opposite to the angle A is known as opposite side (BC), the side which is opposite to 90 degree is called hypotenuse side (AC) and remaining side is called adjacent side (AB).

So, the height of the aeroplane above the ground is 9.192 km.Here AB represents height of the balloon from the ground. His angle of elevation to the top of the building is 70°. is the angle between the horizontal line of sight and the object.If a person stands and looks down at an object, the is the angle between the horizontal line of sight and the object.Trigonometry can be used to solve problems that use an angle of elevation or depression.He stands 50 m away from the base of a building. One group initially planned on taking a picture of a student pointing a ruler at the top of the building and then later use that picture to calculate the height.

Calculate an estimate of the height of the building. The heightof an object is calculated by measuring the distancefrom the object and the angleof elevation of the top of the object.

In the right triangle ABC the side which is opposite to angle θ is known as opposite side (AB), the side which is opposite to 90 degree is called hypotenuse side (AC) and remaining side is called adjacent side (BC).But, sin θ  =  Opposite side/Hypotenuse side  =  AB/ACAn aeroplane is observed to be approaching the air point. Find the distance between the tree and the tower.A man wants to determine the height of a light house.

Here, AB represents height of the building, BC represents distance of the building from the point of observation. Label the sides of the triangle \ (o\), \ (a\) and \ (h\). The three trigonometric ratios; sine, cosine and tangent are used to calculate angles and lengths in right-angled triangles.

Give your answer to an appropriate degree of accuracy. He measured the angle at A and found that tan A = 3/4. Our team of exam survivors will get you started and keep you going.

What is the height of the light house if A is 40 m from the base?A balloon is connected to a meteorological station by a cable of length 200 m inclined at 60 degree angle .

Here AB represents height of the tower, BC represents the distance between foot of the tower and the foot of the tree. Find the height above the ground.Here AB represents height of the airplane from the ground.In the right triangle ABC the side which is opposite to angle 50 degree is known as opposite side (AB), the side which is opposite to 90 degree is called hypotenuse side (AC) and remaining side is called adjacent side (BC).

Now we need to find the distance between foot of the tower and the foot of the tree (BC).So, the distance between the tree and the tower is 51.96 m.Here BC represents height of the light house, AB represents the distance between the light house from the point of observation.
