Question

two boys stand on either side of a hill, first boys sees rhe top of the hill at an elevation of 60 degree, and the second boy sees it an elevation of 30 degree, the distance between the boys is 400 metres. the hil and the boys are on the same line, draw a rough figure based on the given details, what is the height of the hill​

Answer 1

Answer:

Since this forms a triangle which is right angled at 90 degree so we can use trigonometry to answer this question.

Step-by-step explanation:

Here, sin60=AC/AB ...Now we get Ac =sin60×ab

Therefore AC = (√3)/2 × 400

so AC=200√3 m

now in triangle adc we have angle cad=30degree

and so Sin 30 = cd/ac here u may put the value of ac and sin30 and u have the answer for the height of hill....
