ORTwo windmills of height 50 m and 40.13 m are on either side of the tede of the field. Aperson observes the top of the windmills from a point in between them. Theangle of elevation was found to be 45 and 30°. Find the distance betweenSomeApp!the windmills.403 m |

Answer» Answer: 119.5 m Explanation: In the first windmill: angle of elevation was observed to be 45 degree and the HEIGHT of the mill was 50 m tan 45=50/A. (tan 45=1) A=50 m in the second windmill: the angle of elevation was observed to be 30 degree and the height of the pole is 40. 13 m tan 30=40.13/B. (tan 30=1/√3) B=69.5m. (√3=1.732) now adding a and b we will get the answer of DISTANCE between the two poles a + b is equals to 50 + 69.5 is equals to 119.5m |
