3-D Trigonometry New problems please help

Can someone help me to draw diagram from this question:

David walks along a straight road. At one point he notices a tower on a bearing of 053 degree with an angle of elevation of 21 degree. After walking 230 m, the tower is on a bearing of 342 degree with an angle of elevation of 26 degree. Find the hieght of the tower correct to the nearest metre.

Edit: This question has been drawn by Soul Teacher but when I tried to solve it. There are 2 different solutions (one is 88 and one is 74)


New question: please click on the attach file. I have just typed it up.

Usually, but not guaranteed for everytime. Sometimes you will be asked to draw a diagram with the given information for a mark or two.
