You notice a horizontal outcrop of an unfolded stratum with a midline 50 meters below the top of a vertical cliff, with a thickness of 3 meters. After climbing to the top of the cliff to investigate further, you find another outcrop of the stratum on the flat clifftop, 2.6 meters wide.

61. What is the true thickness of this stratum in meters? (3)

62. How far is the midline of the second outcrop from the cliff edge in meters? (2)

The first thing to do when encountering this kind of picture is drawing a picture and labeling relevant angles and lengths. In this case, you would probably only need to draw a cross section. From there, solve for the angles and remaining lengths using some trig calculations. If you need more help, I can attempt to draw a picture.

Yes can you draw the picture please? I would really appreciate it. Thank you!

Here's a start to the problem https://imgur.com/a/cZPCFRV

The solution to 61 is left as an exercise in trig
