Hello students, given that a part of waterfall is having a height of h and the angle of elevation to the waterfall is 62 degree.
00:16
Let us consider the highest point as a and this is b and this is c.
00:23
The angle of elevation from the far side of the pool to the top of the waterfall is 62 degree.
00:29
So, let us consider this as theta and the distance is 120 feet.
00:39
So, the distance is 120 feet.
00:43
First, we have to find the height of the waterfall.
00:56
To find the height, we use the trigonometric formula that is sin theta equal to opposite side by hypotenuse side.
01:25
Here, theta is represented as 62 degree.
01:28
Therefore, sin 62 degree equal to the opposite side is h and hypotenuse side is 120 feet...
